Want to grab hostname out of filename?

I want to be able to parse out the HOSTNAME of this example below, any help would be appreciated I am learning regex as I go. It is for scripting no particular language:

filename.08ad562.HOSTNAME-2012.08.02.13.50

HOSTNAME is the only part that is between a period and a hyphen?

Code:

(?<=\.)[^-]+

Did not work it gave me this:

838a8dad.v210
08.02.13.50

Here is the an actual filename: explorer.838a8dad.v210-2012.08.02.13.50

In this example I only want v210 which is the hostname but hostnames will vary

Hmm, yes it would do that...

Code:

(?<=\.)[^.-]+

...Where's the lookahead? Why isn't the lookahead in there?

Code:

(?<=\.)[^.-]+(?=-)

I'm surprisingly off the ball today. Time for a lunch break.

Sweet that worked, thanks now I can continue what I was doing, So it was a look behind, not character in set one or more times, and look ahead. Thanks thats awesome!
