Previously, it was not possible to log host names. With this update, squid no longer sends malformed DNS PTR queries, and as a result, host names are logged as expected.

Squid send malformed PTR query for IPv6 address. This affects logging FQDN.

patch is in the upstream bug

Comment 5 Ondřej Pták 2015-06-18 21:57:46 UTC
If squid is configured to log fqdn, there should be hostname instead of host ip. With squid-3.1.10-29, there is correctly hostname displayed in log, but with previous version of squid reverse lookup failed an ip address was displayed instead.

squid.conf (part)
log_fqdn on
logformat fdqn %>A %>Hs "%rm %ru"
access_log /var/log/squid/fdqn.log fdqn
