I will certainly agree, my story about changing .local to .home to make
things work again has a continuation that I eventually use the same
domain inside the nat and outside, with a split DNS. It gives a bit more
work for DNS administration but makes life very easy for clients, they
see no difference because the names are the same but resolve to
different IPs. I believe the load on the roots is not influenced by this.
If having different internal and external domains gives problems this is
a possibility, if the purpose is to isolate internal vs. external hosts,
use different subdomains.
