On my ISP sometimes I notice they dont change them for months at a time!!!!

I have had the same IP for 4,5 months!! (A staff member can verify my findings)

I always unplug my modem after im done so thats how I know the IP truly is not being rotated........

Exclamation How to force a MAC address change

Actually the device has a lot to do with your assigned IP address, which on some routers is changeable for the purpose of MAC address cloning. If you're able to edit the "WAN MAC address" in your router settings, you can "trick" your ISP into thinking you have a new router - or the same router if it's another model (and you want to keep your existing dynamic IP).

Just change the last WAN MAC address character to a hexadecimal number or letter, power it (and the modem) off for a few minutes, then back on. The ISP will usually give you a new IP address after everything reboots.

Later, you can reset the WAN MAC address to its default and repeat that cycle to change it again. It seems to work consistently with Comcast, at least.

The common ipconfig /release, /renew tip tends to be futile because the ISP still sees the same MAC address.
