That is probably question for zypper team, I will try to follow up.
E.g. for direct MirrorCache (or MirrorBrain) requests you can overwrite IP with X-Forwarded-For header, e.g.:

curl -H 'X-Forwarded-For: 142.250.185.206' http://mirrorcache.opensuse.org/rest/myip
{"country":"US","ip":"142.250.185.206","region":"NA"}
