Some of our tests require internet connectivity / an IPv4 stack
We got word from an onion service operator that they had to disable some of our tests because they wouldn't work in their ipv6-only setup.
In particular they mentioned the following tests (or functions): get_if_addrs_list_internal, get_if_addrs_list_no_internal, get_if_addrs, status_vote_current_consensus_ns
We should probably investigate this.
To upload designs, you'll need to enable LFS and have an admin enable hashed storage. More information
