Be very careful when using dot notation combined with delete. The command itself can remove anything, even if you are located in a different directory than you might expect, especially when operating as the root user.

@Sven,

To include checking IPv6 address alongside IPv4, you can modify the script as follows:

# Check Internal IPv4 and IPv6
internalip=$(hostname -I)
echo -e '\E[32m'"Internal IPv4 :" $tecreset $(echo $internalip | awk '{print $1}')
echo -e '\E[32m'"Internal IPv6 :" $tecreset $(echo $internalip | awk '{print $2}')

# Check External IPv4 and IPv6
externalip=$(curl -s ifconfig.me)
echo -e '\E[32m'"External IPv4 : $tecreset "$(echo $externalip | awk '{print $1}')
echo -e '\E[32m'"External IPv6 : $tecreset "$(echo $externalip | awk '{print $2}')
