Note also that this can change very rapidly. I've seen Windows Update
DNS TTLs of 300 seconds and yes, the destinations changed on expiry.
That said, I've had a squid cache for several hundred devices with the
primary destinations of Apple/Windows updates (it's a tech support
group and they're constantly imaging/updating machines) for months and
they Just Work. The proxy is inline, running in intercept mode on
their firewall.
