Yes, exactly. With no DNS, you're far more likely to lose mail than
if you have DNS but no responding mail servers. Plus, if you have to
move to another facility, you're looking at 24-72 hours for name
server changes to replicate worldwide, while if you have a secondary
DNS offsite you could be back up and running immediately after setting
up new servers.

assuming both subnets are within that network, that would work. I
doubt you have that whole /16 though, and if you configure your
network as including that, you won't be able to communicate with
anything that's actually on that network and is outside your network.
