Re: How long are Comcast DHCP leases? in Comcast HSI http://www.dslreports.com/forum/r14341659 en Sat, 28 Nov 2009 19:03:11 EDT Sat, 28 Nov 2009 19:03:11 EDT Re: How long are Comcast DHCP leases? http://www.dslreports.com/forum/remark,14361196 Macflash : The DI-624 does not post its the amount of lease time its connection to the internet has, only the expiration times of the leases it gives to its clients. The only way I can see the length of the internet lease is to connect my computer directly to the cable modem and run ipconfig. You can make a guess from the DI-624 log though from when the router starts trying to renew its lease. Its usually half way into it.
It looks like Comcast may have made some changes around here lately. My IP address went from 24.xxx.xxx.xxx to 68.xxx.xxx.xxx. Ever since then my lease has been only an hour. This has been going on for about three weeks.]]> http://www.dslreports.com/forum/remark,14361196 Wed, 14 Sep 2005 10:44:22 EDT Re: How long are Comcast DHCP leases? http://www.dslreports.com/forum/remark,14360559 Kip patterson : The DHCP information in the modem logs is for the modem's Wan-side IP.

Once with a new installed router (MAC change), the second when they switched me from the ATTBI servers to the Comcast servers, and when I upgraded my router to a WRT54GS last summer.]]> http://www.dslreports.com/forum/remark,14350672 Mon, 12 Sep 2005 22:04:17 EDT Re: How long are Comcast DHCP leases? http://www.dslreports.com/forum/remark,14347018 WickedWinter :

They do uses a persistant lease system, as long as you are on once a week you will probaly get the same IP for many months or years.
Yup, even when I'm out of town for more than a week, the router is on.
