Choose ipv6 if it is more suitable.
Checks order:
- check config values (it is faster) - eportal setup and FORCE_IPVx
- then check each proto availability using HEAD requests
- then check if we have server_id, it means we don't expect an ip license
- and finally we need to check if there is an ip license
