Programmatic Ping Alert
We currently lack the ability to white list domain names on our firewall, so I have to do everything via IP. Recently I’ve come across an issue where a company won’t give me their external IP’s because they can change, or so they say. For several weeks I’ve pinged the IP’s and it has always been 1 of 4 IPs. Has anyone created some kind of ping alert that does something like “ping easypost.com and api.easypost.com if the IP’s returned are not in 169.62.110.130-169.62.110.133, alert me” I’m not much of a programmer myself so I’d need something pretty “plug and play”.
TIA!

plug-n-play, not likely for this use case.
It seems like you need to monitor the DNS resolution and update your synthetic check based on the IP that the DNS resolves to. Does that about sum it up?
If so, this is definitely not going to be something that’s just plug-n-play. You’ll need to write a microservice to monitor the DNS and whenever the resolved IP address changes, hit the LM API to patch the synthetic check to update the IP address. All of this is doable, but depending on your level of comfort, you may want to pursue other avenues (start preaching the we-need-to-be-able-to-whitelist-domains argument).
