Can squid forward DNS queries to a DNS server? – Stack …
Looking at What is Squid?
Squid is not a DNS proxy. It does some local DNS caching for its own purposes.
Squid keeps meta data and especially hot objects cached in RAM, caches DNS lookups, supports non-blocking DNS lookups, and implements negative caching of failed requests.
One way to think about it is that as “web” proxy, Squid lives in the application layer. TCP connections (and UDP datagrams) cannot simply be passed around as they would in lower levels. Applications must understand the protocol that comes out of the end-point, and that typically means that their functionality can be described as a white-list of protocols:
Squid is a high-performance proxy caching server for web clients, supporting FTP, gopher, and HTTP data objects.
In short, your question was: “.. squid understand its a DNS query and forward those queries to the dns server set in ”
Squid might listen to UDP (I didn’t check this), but even if it did, it would not understand the inbound DNS traffic.
