In MythTV, all settings are indexed against the machine hostname in the
database.  When MythWeb scans for accessible frontends, it looks up the
port and hostname for any frontend listed as having the network control
port active.  It then relies on a functional resolving framework to be
available on your system to find the host.

Backends, on the other hand, are connected using the IP.  When frontends
or MythWeb want to connect, they look up the address for that hostname
through the database, rather than relying on the host's resolving
capability.  He is suggesting you patch MythWeb to use that address when
available, and then run mythtv-setup on each frontend to define that IP as
if you were going to run a backend.
