awk does pattern matching, o you can ditch the grep stage and use

 awk '! /myip/ {print $1}'

You could use awk to search for the GET patterns too, not only saving yet
another process, but making sure that no one else, including you next
month, can work out what the command is supposed to do.

sort -u would save having a separate process for uniq, but I've no idea
if it's faster. It's only worth using sort -u if you would use uniq with
no arguments.
