That is, the entire 127/8 range is "routed" through 127.0.0.1 and will look like that to the server. I see similar entries on NetBSD. Confirming that guess, I see this behavior on RHEL8, with no particular OpenSSL involvement: $ psql -h 127.0.1.1 psql (16devel) Type "help" for help. postgres=# select client_addr from pg_stat_activity; client_addr ------------- ... 127.0.0.1 ... Moral: don't try to use addresses in that range as real addresses. regards, tom lane
