Other tools you may find usefulVirtual Hosts Finder - check what domains are connected to the selected IP or server
Virtual Hosts Finder in the Webp toolkit allows you to conveniently check what virtual hosts and domains can be configured on a given IP address or host, without manually digging into WHOIS, without searching the Certificate Transparency logs yourself and without installing specialized software like pentester tools. You enter the IP or host name, select the data sources for analysis, or add your own list of domains to check and with one click you get a clear table with potential virtual hosts, information about where they come from and short comments for further analysis.
This tool was created with they are thinking about people who want to quickly see what domains may be on a given IP or what virtual hosts are probably configured on a specific server, for example when changing hosting, tidying up the infrastructure, analyzing their own company environment, security audit or simple curiosity about the configuration of services. Webp's Virtual Hosts Finder combines several data sources into one simple interface, so you don't have to separately visit WHOIS sites, CT log viewing tools, or write scripts that check potential hosts on a given IP one by one.
Why do you need Virtual Hosts Finder and in what situations is it useful
Modern hosting very often operates in a shared model, where many different domains, subdomains and environments can be located under one IP address, which on the one hand is economical, but on the other hand makes it difficult to quickly understand what is actually running on a given server. This is where the Virtual Hosts Finder comes in, which in a clear form helps collect potential virtual hosts on a selected IP in one place, suggests which domains can be associated with a given infrastructure and facilitates both administrative arrangements and a preliminary analysis of security and the domain environment.
Typical uses for website owners and brands
- Checking what domains may be on the same IP as your website to assess whether the environment is tidy and whether you are hosting forgotten test projects.
- Server IP analysis before migrating to new hosting to make sure you are taking all important domains with you and not leaving behind old environments that were once used for campaigns or landing pages.
- Organizing the company infrastructure, in which new domains, subdomains and services have been added over the years and today it is difficult to say at first glance what is still used and what can be safely disabled.
Scenarios for SEOs, analysts and technical people
- Quick understanding of what domains may be associated with a specific IP address, which can be useful in back-end analysis, network of own websites or tracking old projects from the same infrastructure.
- Initial reconnaissance when auditing the security of your systems, when you want to collect domains pointing to IP data in one place and make sure that they are all up to date and properly managed.
- Support for people from IT departments who take over someone else's infrastructure and need to quickly find out what virtual hosts can be configured on specific servers or network addresses.
How Webp's Virtual Hosts Finder works step by step
The Virtual Hosts Finder add-on is built as an easy-to-read tab with a form and table of results that, in the background, uses several different sources, including WHOIS, Certificate Transparency logs, and your own list of potential hosts, and then combines them into one list of probable virtual hosts associated with the selected IP or host. The whole thing is designed so that the user only sees a simple form with fields described in Polish and a clear list of results, without the need to understand the technical details of how these services work.
Most important fields of the Virtual Hosts Finder form
- IP address or host- the main field in which you enter the IP address or host name, for example
1.2.3.4orexample.com, and the tool treats this value as a starting point for further analysis. - Analyze WHOIS data- a switch that allows you to enable additional checking of WHOIS information, if available, in order to extract potential clues about related domains and the owner of the address.
- Try to find domains in the Certificate Transparency logs- an option that adds CT logs (crt.sh) to the analysis, from which it is possible to detect domains for which SSL certificates associated with a given IP or host have been issued.
- Use your own list of potential hosts- a place where you can paste your list of domains and subdomains, each on a separate line, so that Virtual Hosts Finder checks them in the context of the indicated IP.
- Maximum number of hosts in the result- a limitation that allows you to set an upper limit on the number of hosts in the table, making the result more transparent and tailored to your work.
What happens when you click the search for virtual hosts button
- Virtual Hosts Finder takes the IP or host from the form and tries to get basic data such as IP address and reverse DNS to build a startup context for further analysis.
- If you check the appropriate options, the tool will attempt to use WHOIS data and Certificate Transparency information to find domains that may be associated with this address or host.
- If you have provided your own list of potential hosts, Virtual Hosts Finder will combine all the results and present them in one table, adding a column with information about where the domain comes from.
- Once the process is completed, you see a clear list of potential virtual hosts along with basic data, which can be treated as a basis for further manual or automatic analysis.
How to read Virtual Hosts Finder results and interpret sources
After successfully running the search, you will see a section with basic information about the target being examined and a table with the virtual hosts found, in which each line represents one potential domain or host associated with the selected IP. Thanks to the host, IP address, sources and comments columns, you can easily distinguish domains found in WHOIS, Certificate Transparency logs or on the basis of reverse DNS and your own list, which significantly facilitates further analysis and decision which entries are the most reliable.
| Results element | What | shows How you can use it |
|---|---|---|
| IP address | The IP address associated with the specified host or directly entered in the form that forms the basis of the analysis. | Lets you make sure you're working on exactly the IP you want, which is important for migrations, DNS changes, and looking for old environments. |
| Reverse DNS (PTR) | The host name resulting from reverse DNS, if set, which often reveals the primary server or carrier-assigned name. | You can treat this entry as a clue to your hosting provider or the original server designation in the infrastructure. |
| Host / domain | A potential virtual host, i.e. a domain or subdomain which, according to the collected data, may point to the analyzed IP. | Each such entry is a starting point for further verification, checking the page in the browser, analyzing the configuration or deciding to organize the environment. |
| Sources | Information where the domain comes from, for example from WHOIS, Certificate Transparency logs, reverse DNS or from your own list. | If you see a domain appear in several sources, you may consider it more reliable and more important to check further. |
| Comments | Additional technical comments prepared by the tool that may address specifics of the detection or possible limitations. | They are worth reading for more advanced analyzes and when you are preparing a reconnaissance report for yourself or your team on your own infrastructure. |
Virtual Hosts Finder and security and good usage practices
Checking what domains can be connected to a given IP is a typical element of infrastructure reconnaissance and analysis, which is used both by administrators and security specialists, as well as by ordinary website owners interested in organizing their projects. For this reason, Webp Virtual Hosts Finder emphasizes the clear communication that you should only use it within your own systems or environments for which you have formal permissions or permission from the owner, because much of the infrastructure on the Internet is not intended for arbitrary scanning by third parties.
Using Virtual Hosts Finder Safely and Fairly
- Analyze primarily your own domains and servers, corporate projects, or systems for which you are formally authorized to perform reconnaissance testing.
- Please respect your hosting provider's terms and conditions and local laws as some reconnaissance practices may be restricted or regulated in individual countries.
- Treat the Virtual Hosts Finder results as a starting point and not as a final and comprehensive view of the entire infrastructure, as many servers may intentionally limit the visibility of their services in public sources.
How to Build a Domain Analysis Process Using Virtual Hosts Finder
- First, collect the primary IPs and hosts of your servers, then drop them into Virtual Hosts Finder one by one to get an initial list of potential virtual hosts for each address.
- Then proceed to manually verify your most important domains by visiting sites in your browser, checking SSL certificates and DNS configuration to spot projects that need attention.
- Finally, organize the list by dividing it into business-active domains, auxiliary domains such as test and staging, and projects that can be expired, which also improves the security and transparency of the infrastructure.
Virtual Hosts Finder FAQ in Webp
Does Virtual Hosts Finder work fully online in your browser
Yes, Virtual Hosts Finder is part of the Webp toolkit and runs directly in your browser, so you don't need to install any additional programs or plug-ins on your computer. You go to the tool's website, enter the IP or host, select selected data sources, click the search button and after a while you see the results in the form of a table with potential virtual hosts and basic information.
Where does Virtual Hosts Finder get information about domains
The tool uses several sources, for example basic DNS data, PTR records, available WHOIS information and Certificate Transparency logs, as well as a list of domains that you provide in the own host list field. It then combines this into one list of potential virtual hosts, adding in the sources column where the information comes from, so you can easily see which domains appear in several places at the same time.
Will Virtual Hosts Finder show all domains on a given IP
In practice, 100% completeness cannot be guaranteed because some configuration may be hidden or intentionally limited, and some data in public records may be delayed or incomplete. Virtual Hosts Finder is intended to be a convenient reconnaissance tool that provides a good starting point for further analysis, but it is always worth comparing its results with the real server configuration, administration panels and other sources of information about the infrastructure.
Why do I see a message about an invalid IP address or host
The most common reason is a typo, adding a protocol such ashttps://or the entire path instead of the domain itself, or entering a string of characters that is not a valid IP address. In this situation, simply correct the entry in the form, leaving only the hostname or clear IP address, and then run Virtual Hosts Finder again to check the results for the appropriately formatted target.
Can I save the virtual host search results to the
report The easiest way is to select the table with the results directly in the browser and paste it into a spreadsheet or text document, where you can add your own comments and priority markings. Many people use Virtual Hosts Finder as the first step to building an audit report of their own domains, which is why this form of data copying works very well in everyday work.
Is it legal to use Virtual Hosts Finder to analyze someone else's infrastructure
It depends on local laws and regulations of service providers, but it is good practice and in line with the principles of an ethical approach to security to limit yourself to systems that belong to you or your organization, or those for which you have express permission to test. Webp provides Virtual Hosts Finder for people who want to organize their own infrastructure, so always use this tool responsibly and in accordance with applicable law.
Check what domains may be hanging on your IP with one click
Instead of manually jumping between several websites, copying WHOIS results, pasting domains from Certificate Transparency logs and running scripts to check your own host lists, run Virtual Hosts Finder in Webp, enter the IP address or host and let the tool put this information into one clear table. Thanks to this, you save time, have a better overview of your infrastructure and can immediately decide which domains and environments require cleaning and which are already configured exactly as they should be.
