I know you have numerous PCs.

Do you run your own local dns server? Since you have numerous machines you
should. Set it up to forward non-cached lookups to a good dns server. No need
for that good dns server to be your isp's.

Dns is a pretty lightweight service, so the recommendation even 20 years ago
was to dedicate a low performance PC to dns. The reason for that is uptime for
your local dns server is very important. Having a local dns server means 99%
of dns lookups will be handled at local lan speeds. It also means the cache of
names/ips is shared by all your machines.
