See also this question, which asks pretty much the same thing, and got pretty much the same answer. (ie don't use regex for this!)

A regular expression really isn't well suited to this sort of validation. Gareth's answer provides a much more sensible solution.

If, for some reason, you absolutely have to use a regex then it will probably look something like this:

^(?:[0-5]?[0-9]{1,4}|6[0-4][0-9]{3}|65[0-4][0-9]{2}|655[0-2][0-9]|6553[0-6])$

Don't use a regular expression.

if(i >= 0 && i <= 65536)
