[squid-users] dns_packet_max

Still reading all the options, noticed dns_packet_max is off by default. My
squid uses dnsmasq, that has EDNS on by default and it "defaults to 4096,
which is the RFC5625-recommended size"

In this case what will happen then? dnsmasq may receive EDNS up to 4K,
which squid by default only takes 512Byte.
warns some older resolver does not like EDNS, but dnsmasq has this feature
on by default...

Thinking about setting up "dns_packet_max 4096" and see what happens...
