I am a service provider and a site is sending me an IP address to add for their EZproxy that seems odd, how do I troubleshoot the IP address?

  • You are a Service Provider and a site that uses EZproxy and they are sending you an odd IP address to add to your allowed list and you want to troubleshoot the IP address
Applies to
  • EZproxy

If a site is sending you an Odd IP address and you want to troubleshoot it, you can take these steps::

  1. Go to Arin Who Is User Interface.
  2. On the top right, put in the IP address, or if they have an IP address range they sent you, then put in one IP address within that IP address range.
  3. You will get a result.  Sometimes, you will get a message that you need to search a different Arin Whois site.
  4. If you get a message to go to a different site, go to that site and search the results.
  5. You can then better determine if it is part of the organization and you will then have the information to make a decision on your next step.
