First Off: Renewing a Lese Will NOT Get You A New OUTSIDE (Public) IP

A common misconception is that when you renew your DHCP lease, you will not get a new IP address to the outside. Instead you will get a new identifier on your OWN network.

Here’s an example: When you start your PC and you have DHCP set to “automatically”, then the DHCP server will assign an IP address to your computer out of the 254 available that are available on your network. When you assign a static IP, the DHCP server will always use the same IP address

A Lease Will Expire After A Pre-Defined Time

The so called “lease time” that can be configured via the TCP settings will renew your internal IP addresses – if you set the lease time too short you will frequently get connection interrupts

1 Check Your IP Settings

1. Step Open a command prompt windows by entering cmd either into the search menu on your Start menu (Windows 7) or on Windows 8 hit CTRL + F on a Start Screen and enter cmd. If you need help with this step, read this

3. Step Scroll down and search for your default Ethernet adapter usually called Ethernet.

You will get information about the DHCP lease obtained, DHCP lease expires, DHCP Enabled options

4. Step In this case the DHCP lease won’t expire for DAYS! So the lease time is quite long

2 Renew Your DHCP Lease

1. Step Enter ipconfig /release and hit Enter

2. Step Your Ethernet adapter will now release the current lease – HOWEVER it will not auto-renew the lease, which is why this will happen

3. Step Now enter this into the command prompt and hit Enter
