Router DHCP Lease

Hi All

IM just curious to see what virgin media lease time is for an assigned public ip address, Im aware the lease will expire after so long but if that device is still connected it would normally get the same mac address

 

What i notice is if i change my 3rd party mac address via my wifi router i can get a new IP address assigned from VM - My question is how long will it be before my old ip address i used to have will be put back in the pool for someone else to use?

Re: Router DHCP Lease

Why would you want to change your external WAN IP address?  Normally VM IP's a quite sticky even though they are DHCP.

I hope by releasing your old IP into the pool it's not going to bring a world of pain to whoever gets it 😉

Re: Router DHCP Lease

Ive noticed 1 or 2 services saying the ip address was blocked, so i changed the mac address to get a new dynamic ip on my wifi router and was able to get back onto them services with no issues.

i was just curious thats all on how long the res is held for

Re: Router DHCP Lease

My IP address changed a few weeks ago, due to reconfiguration, and the old address went straight back into the pool. My monitoring script noticed it and when it went to change my Thinkbroadband display I could see the old one was still active. I think it depends on how many free address there are at the local ‘headend’.

This was exactly my point. Just hope whoever gets your old IP will not be using the same services .....

Lets face it them service and VM plus routing to a given services can take their time to fix the reason why its not working in the first place.
