Unclear It is not clear where Claude Code uses this check, so whether it changes any request you make is not known.
What
A hostname is the name part of a web address, such as the part before the path in a URL. Claude Code now has a check that treats hostnames ending in certain suffixes as private or internal rather than public. The suffixes include:
.consul.corp.ts.net.onion.i2p.xip.io
Other suffixes for internal networks are on the list as well.
Why
This can change which addresses Claude Code counts as private, for example when it decides whether a request is safe to make or should go through a proxy.
Something disagreesSomething we can check disagrees with this entry, or the writer said they could not settle it.
