Shell Programming and Scripting

Newbie to bash here. I think this is fairly simple, but I have searched and cannot figure it out. In the code below, I am searching an array for an IP address, and then printing the IP address if found. However, I would like to print the actual variable found such as 2.2.2.2=2, but cannot figure out how to find the actual location of the found variable in the array. Any help appreciated!

Code:

#!/bin/bash

IPs=("1.1.1.1=1" "2.2.2.2=2" "3.3.3.3=3")

IPAddr="2.2.2.2"

  if [[ ${IPs[@]} =~ $IPAddr ]];

        then
        echo "FOUND: $IPAddr"

  fi

Something like this?

Code:

#!/bin/bash

IPs=( "1.1.1.1=1" "2.2.2.2=2" "3.3.3.3=3" )

IPAddr="2.2.2.2"

for i in ${IPs[@]}
do
  if [[ $i =~ $IPAddr ]]
  then
    echo $i
  fi
done
