How to determine what your DHCP server is on Linux | how to determine your dhcp server ip address

I encountered a problem yesterday where my IP was not changing, I should have gotten a new lease from the DHCP server.

I needed to find which server was giving me my leases, I didn’t know where this information was stored.

Visibility when your IP changes and is updated by no-ip | email notification when ip changes home adsl nbn bash script

My new internet connection with NBN changes the IP on a regular basis, but I wanted visibility as to how often.

So I’ve written a bash script which records your IP and date, once it changes it records your new IP and sends you an email to notify you of the new change.

This is completed by querying your no-ip dns record.
