What is the IP for outgoing PHP requests?

Question

PHP

Hello,

To access the API, I needed to tell the IP from which the requests will originate.

I indicated the one that the hoster writes - but I was told that there were no calls from this IP. Then the technical support advised me to nslookup адрес_ftp_сервераfind out the real IP of the site using the command. It is indeed different from the IP of the whole server.

Therefore, the question arose: when a site makes outgoing connections / requests to other sites, does it burn its real IP? Does CloudFlare hide the real IP address of outgoing requests or just the server IP?

I would be grateful if you explain why the IP of the server and outgoing requests are so different.

Answer 1

From the console, you can find out "your" ip like this:
wget https://ipinfo.io -qO-
If they are dynamic, then of course, it makes no sense to send new ones to api technical support every time.

Answer 2

If you snoop for cloudflare but make requests to other apis with a curl and other tools, then you burn the ip of your server / vds / hosting
