I suggest alwasy starting with the simplest expressions and testing them to be sure you know how they work.
For starters:
grep "190.68.213.193" will match your example IP, but it will ALSO match "190x68g213y193". This is because "." means "any character"
Try this:
Code:
grep "190\.68\.213\.193" filename | grep -v "8080"
First, find all lines containing the specified IP, then---from those lines---find the ones that do NOT contain "8080"
