Something that's puzzling me about DHCP and DNS. On the individual
hosts, be they Linux, Windows, whatever, you have to specify a hostname.
If this system uses DHCP to get it's IP address, the DNS may or may not
resolve to the hostname that that specific system identifies itself
with. Is there a way to make sure that no matter what IP address the
DHCP server gives a computer, it's name will always be consistent?

Ex: let's say I want to FTP from one system to another. The server side
just got a new IP lease and I don't know what it is. Can I just FTP to
<systemname> and access the system I want? Or is this just not possible?
Should I instead just give permanent IP addresses to those systems that
will run servers?

I'm also wondering because in the Windows world, the box name is
consistent, and you can always access it through \\name\share. Granted,
this is SMB and not DNS, but still...

Thanks!
