Answer 1

Just another option, for the sake of showing different options:

(?<=^//)[^/]++

The server name will be in \0 or $0 or simply the result of the function, depending on how you call it and what your language offers.

Explanation in regex comment mode:

(?x)      # flag to enable regex comments
(?<=      # begin positive lookbehind
^         # start of line
//        # literal forwardslashes (may need escaping as \/\/ in some languages)
)         # end positive lookbehind
[^/]++    # match any non-/ and keep matching possessively until a / or end of string found.
          # not sure .NET supports the possessive quantifier (++) - a greedy (+) is good enough here.
