Hi Amos
thank you for very valuable response. I can confirm that amending
default url_rewrite_extras value did the trick!
thanks

Hello guys
following the original thread " Squid 4.9 Client IP PTR
lookup on connect"
I am observing exactly same bahavour on
squid-4.4-8.module_el8.1.0+197+0c39cdc8.x86_64 on CentOS 8.
Certainly 4.4 is older than 4.9.
At first I was suspecting some squid module (auth helper
(gssapi/ntlm/basic), URL rewriter) or syslog (which we use for sending
access logs to remote server) but those DNS queries are coming directly
from squid process (same as the one doing standard forward DNS lookups).
The URL-rewriter input includes the rDNS name of the client IP. I expect
your Squid is trying to fetch that information to send the re-writer.

If that information is not actually needed by your re-writer, then
configure the url_rewrite_extras directive to alter what gets sent.
