You can do this by using IFS in bash.

• First read the first line from file.
• Seoncd convert that to an array with = as delimeter.
• Third convert the value to an array with ; as delimeter.

Thats it !!!

#!/bin/bash
IFS='\n' read -r lstr < "a.txt"
IFS='=' read -r -a lstr_arr <<< $lstr
IFS=';' read -r -a ip_arr <<< ${lstr_arr[1]}
echo ${ip_arr[0]}
echo ${ip_arr[1]}
