I’m wondering if it is possible to call out to an IP address using HttpService? Are you able to do this, or do you have to call out to an FQDN? I’m wondering cause I’m thinking of making an web server and I don’t want to have to spend more money on an FQDN.
It is possible to use an IP address, although I don’t recommend it for anything long term because most IP addresses are dynamic. As an example, Google’s website can be in several different ranges of IP addresses at any time (source).
Edit: Actually ran dnslookup twice for google.com and I got 2 different answers for IPv4.
If you’re running a server on AWS the public IP should not change. I think this is the case with most hosts.
You can access an IP address through Roblox just like you would any website.
You could use serveo, which works like a reverse proxy with a domain, they also allow custom domains.
