sed 's/$/:80/' ips.txt > new-ips.txt

# Multiline sed commands are useful when we want 
# to implement multiple find/replaces at once.

# Different ways to do this:

sed '/[long1][long2]/
    s//[long3][long4]/'
Or maybe like:

sed "$(
    printf 's/[%s][%s]/[%s][%s]/' \
        long1 \
        long2 \
        long3 \
        long4
)"
Or with a heredoc:

sed -f - <<SED file.txt
s/\
[long1]\
[long2]\
/\
[long3]\
[long4]\
/
SED
