Shell script to parse ip:port from a text file

I get daily a text file with ip:port, one per line, example:

11.22.33.44:80
22.33.44.55:8080
33.44.55.66:7777

I would like to parse the first ip and port in two different variables, then write them into another file, wait exceution of a program that use these variables, loop this cycle to pass all the ip:port to the file and execute program.

How can I do that?

thank you

A pure bash solution:

while IFS=: read ip port; do
    echo $ip $port
done < in.txt

This has the advantage of allowing you to set variables inside the while loop that remain available after the loop completes.

cat in.txt | sed -e "s/:/ /" | while read ip port
do
  echo $ip $port # or do something with it
