No, this is why there is public space and private space.

This is why you have a DNS server on each of the WPOPs/Clusters for those
that are not multihomed (connected to both at once). These servers update
every day or two (take a look @ how often it changes and modify to suit). If
your connected to the internet, use your ISP's DNS, if your not connected to
the net, use the local DNS server.

This is where having 2 DNS's would work.
If you have occasional connectivity to the internet, you put in your ISP's
DNS server first, then the local WPOP's DNS server IP.

If your connected to the internet, it'll pull the Wireless domain IP from
that DNS, if not, it will recieve a timeout on connecting to the first
server, automatically jump to the second DNS server and then do the lookup
for you, returning a local wireless located IP

As stated above, have a multihomed DNS server on each WPOP that is on 24 * 7
(doesn't even require a 24 * 7 internet connection, just once a day or
whatever while updating takes place).
