Ty. I checked the following https://www.squid-cache.org/Doc/config/netdb_filename/ <https://www.squid-cache.org/Doc/config/netdb_filename/>, and asked google.
2146+
2147+
?
2148+
# {cache_peer ?. no_netdb_exchange } already set earlier
2149+
netdb_filename none
2150+
pinger_enable off
2151+
Icp_port 0 #seems to be default value
2152+
?
2153+
And this issue persists. It seems that NO squid.conf could help with the DNS leak issue.
2154+
Q1: So, does Squid netdb work on the IP level? In that way, squid has unclear ACLs that bring up invisible communications.
2155+
2156+
Q2: Do I have to compile squid from the source code without benefit of automatic community upgrade ? This is really a less preferable option for most users.
2157+
Is there a higher version of squid that comes up with a powerful conf ?
2158+
2159+
>>>
2160+
>>> FWIW, if I have access to a full debugging log collected while reproducing the problem, I may be able to tell you what causes DNS lookups in your specific environment. I discourage Squid admins from studying debugging logs because they are meant for Squid developers and can be very misleading.
2161+
2162+
We can only confirm issues and observe callees from logs.
