Hi @upperking,
Oupppss ! I should have read your post more carefully ! We must take the leading numbers in account ;-))
So, change the Find and Replace zones, as below :
SEARCH (?-is)^\d+\x20(76\.247\.131\.161:\d+).+
REPLACE \1
Notes :
Beware : if the IP address is not exactly the address 76.247.131.161, nothing is then replaced
The part ^\d+\x20 represents any number, beginning a line and followed with a space character
The dot meta character . is escaped with the \ to be considered as a literal
The group 1 is the string 76.247.131.161 followed with a colon, followed with the port number, which is rewritten, during the replacement phase
Cheers,
