You can use canonical names, like server1.domain.com, it should work,
but beware. Make sure you are using a local cached dns server, or make
the same machine also be its own DNS server, and it has a copy of that
domain. This will make the host lookup much quicker, and not be much
of an issue. If you DON'T do that, you will see a performance hit, and
can even see things DIE if you are having any network issues to your
dns.
Example: If these are windows servers, and lets say your domain is
domain.com. you can easily turn on DNS server on your windows 2003
system and tell it to be a SLAVE or secondary server for that domain,
and point to a master dns server. This is the best, because it will
cache all of the host records for that domain on that machine, yet
when a change to the domain occurs on the master, it will filter down
to the slave. This will keep your performance GOOD.
I have dealt with this when using a file share for my files like this:
\\db1.domain.com\webfiles\site
And also using dns lookup on the datasource like:
ds1.domain.com
This allows me to point them to a different server if needed, and not
change code or datasources and such, but you must nail down your DNS
lookups to be extremely fast and ultra reliable.
Lastly, you may also edit and use the /etc/hosts file, which is even
faster than dns.

I have what I believe is a simple question. We are moving our
Intranet to a datacenter located in Dallas. At that location they
are very conscious of adding new servers, moving machines around,
changing IP addresses, etc. They seem to be able to want to mix and
match machines at will. While I agree that hardcoding server names
or IP addresses in code is very bad practice it seems to me that
complete flexibility isn't possible either. For example, according
to the documentation the client.ini file needs to have the IP
addresses of the servers serving Witango specified. For example a
snippet of our client.ini file looks like:
WITANGO_SERVER=Witango1,10.200.10.51,18150:Witango1a,
10.200.10.51,18151
Is it possible to replace the IP addresses with something else
that will resolve to an IP address of must the IP address be
specified? Yes, we can do a global search and replace if we ever
need to move servers but the powers that be want this as flexible as
possible. Thanks for the feedback and thoughts.
