Seth Hall commented on BIT-1042:
--------------------------------

Brian, you can refer to the scripts here: 
   https://github.com/sethhall/bro-junk-drawer/tree/master/domain-tld

There are some examples of dealing with domain names (and I'm avoiding string creation as much as possible which is good for performance).

> print split_all("some string", /^t/);
> I would expect it to not match ^t, but it matches any t in the string.
> output:
> {
> [1] = some s,
> [3] = ring,
> [2] = t
> }
> expected:
> {
> [1] = some string
> }
> tested on bro 2.1 and github master 2.1-824
