Is ip address internal or external?

I have an ip address and I want to know if this is an externally accessible ip address (like customers can reach it) or if it's only an internally accessible ip address (TR internal network only).

Examples: 10.214.134.3, 167.68.5.129, 10.215.35.7

Depending on where you are in the organization you can look up your IP here or contact your platform support group to have this done

In this case your example IP of 167.68.5.129 is part of a VIP pool called Platform-ExternalSiteIGVerticalCheck.19.3.1003. This looks to be accessible on both port 80 and 443, but both have extensive rule sets on them and a quick test from a public server gives me no TCP response.

Certain address blocks (including 10.* range) are internal-only blocks. See [this Wikipedia article][1].

Another approach would be to attempt a ping from an external network. [This website][2], for example, will let you enter an arbitrary ip and attempt to ping it. The inability to ping an ip doesn't necessarily mean it isn't accessible. The firewall could also be configured to block external pings.

Thanks, but I'm not sure I follow your idea. Zipper doesn't seem to clearly identify a vip as only internally accessible on the TR network. It does list one of the iRules on that vip (as you've pointed out) but that doesn't seem to help too much. For example, this vip 163.231.17.180 has an "external" iRule too, but it is really only accessible on the internal TR network.

Highlight over the computer network symbol after searching a vip. Our external vip says PROD EXTERNAL VIPs. I checked your 163.231.17.180 and it is not showing it as an external vip.
