RE: Re: snv URL does not use FQDN

I was thinking that it would be better to test "IP-addr-of(A) =
IP-addr-of(A.B.C)", which is more likely to work, since people often do not
have reverse DNS working.

But that is not safe either, given that a single real host can host multiple
apparent Subversion HTTP servers -- HTTP/1.1 allows one server to use one IP
address, but serve several HTTP host names with possibly overlapping file

Given that "svn switch http://A.B.C/xxx ." can be used to correct any
working copy that is created with an abbreviated host name, it seems to me
that it's safer to not try to solve the problem with a clever but fallable
automatic mechanism, but rather endure with a problem which will cause no
unpleasant surprises.

There are a couple of ways to determine if A == A.B.C. The one that
I've seen used is to determine the IP address for hostname A, then
perform a reverse DNS lookup on that IP address to find out what the
fully qualified name (according to DNS) is.
