HTTP Host doesn't accept IPv6 IPs #1615
Description
Describe the bug
The --http-host flag is passed in to the HTTP server to determine which addresses to bind on here.
We also attempt to resolve the --http-host to an IP to check to see if it is discoverable here.
When providing --http-host to the HTTP server, we append the port suffix. For IPv6 this means the --http-host must be boxed with [XXX]. However, that would cause the resolution of the IP to fail.
To Reproduce
Try to specify an --http-host with either [::1] or ::1. Both will fail.
Expected behavior
We should be able to specify IPv6 literal IPs.
