After some experience with the the relaxed rules for references to
off-site servers we have changed our
process slightly. Instead of putting the IP addresses in the
ucam.biz
zone, we are going to enter them into the IP Register
database, so that these non-CUDN IP addresses appear directly in the
cam.ac.uk
zone.
There are a few reasons for this:
Both the
ucam.biz
and IP Register setups are a bit fiddly, but the database is more easily scripted;It reduces the need for us to set up separate HTTP redirections on the web traffic managers;
It reduces problems with ACME TLS certificate authorization at off-site web hosting providers;
It is closer to what we have in mind for the future.
The new setup registers off-site IP addresses in an OFF-SITE
mzone,
attached to an off-site
vbox. The addresses are associated with web
site hostnames using aname
objects. This slightly round-about
arrangement allows for IP addresses that are used by multiple web
sites.
