I have comcast and want to get a new IP address...
Err... why?
Probably the usual reason -- his IP has been banned by a chatroom or
game server.
That's what I thought. Pity, ain't it?
How do you do this
with Airport Express, comcast cable modem, and OSX?
The same way you do it with any other DHCP system: release and renew the
lease. As DHCP will tend to give you back the same IP that you used to have
(because that's what most people want...) you may have to release the IP,
wait a while, and then renew. If the local Comcast node has a lot of IPs
available, it may be some time before someone else grabs your old IP.
I've heard of people going away for a week and still getting the same IP
when they come back.
Comcast's DHCP leases are usually 8 days. Depending on when you left, you
might need 9 days to clear the old lease. And that might not do it. You may
still get your old IP back.
You could also replace your cable modem. The new cable modem would have a
different MAC address, so Comcast would give you a new IP. Of course, you'd
I don't think the cable modem's MAC address matters, it's the MAC
address of the device connected to it.
I thought it was the MAC of the modem; I've got a bunch of machines behind my
cable modem, and Comcast doesn't change my IP. It doesn't matter, anyway.
Whichever way it is, Comcast will know _a_ MAC, and will store it, and will
tend to give back the IP to that MAC if at all possible.
You could also call Comcast and request a new IP. You'd have to reboot the
modem, and I don't know if they'd give you a new one just because you
wanted
it.
I've never heard of them doing this.
Me, neither. He could try, though. Seems like a better bet than anything
else, unless he wants to disconnect from the internet for 10 days plus...
