IP Not Detected

Post by StefsterHB »

I searched this forum for which I found no relatable answer or question for that matter. Is the search function just not working properly? I find this one hard to believe that no one's asked it.

We've asked clients to use the site to get us their IPv4 IP and several of them have written back telling us that it states "Not Detected"

Would that be because their ISP has them running thru a proxy or they have a firewall or something entirely different? Is there some other way we can get their IPv4? Certain hosting companies, when applying security measures to the server don't allow for IPv6 and we want to ensure that our clients are protected.

Thanks in advance.

Interesting, it's usually the other way around, in that people have IPv4 transit, but not IPv6.

We'll check to make sure nothing other of the ordinary is happening on our backend.

The IP version seen that the top of the two on the homepage is the protocol that was used to connect with our edge network. The second one using javascript to connect out to a dedicated protocol server on the opposite protocol. If you connect with IPv6 the javascript call is made over IPv4. If you connect with IPv4 the javascript call is made over IPv6. If javascript is disabled, then it will fail and show "not detected". While I haven't checked, it's possible that maybe an ad blocker, javascript blocker, or other security extensions are interfering.

I wouldn't expect a firewall or proxy to interfere.

I suppose some obscure mobile service might be IPv6 only, but that would likely cause other problems.

I did some testing on a variety of dual-stack network connections, and all are behaving as expected.

We disabled our IPv4, IPv6, IPv4/IPv6 API that returned just the IP because they were being abused.

Got it. Well I appreciate you taking on all that debugging. Thank you. I'll try and get more information between clients and see if there's a commonality.
