The ^ at the very start of the regex indicated the beginning of the line, as opposed negation. Thus, the regex looks for a typical numercial IP address at the start of a line; if found, it splits the line on whitespace and returns the parts as an array. Mind you, this isn't perfect (an ip of 999.999.999.999 will match though not legit), but it will make sure that any line that starts with something that looks like an IP is treated differently from everything else.
