a 169 ip address is assigned by windows...LOL Comcast wouldn't and couldn't send you one. The tech is very confused...

Also, if the DHCP server was down, they couldn't send you anything....LOL

Not all 169 addresses are 'bad' or non-routable. But, in this case, it is.

Not so MS as a standard ...

Actually it's not a 'Windows' default as much as it is the auto-config protocol (»www.rfc-editor.org/rfc/rfc3330.txt for special addresses and »www.ietf.org/rfc/rfc3927.txt Link-Local). It just happens to be that MS is one of the Authors and uses it heavily.

I've never understood

why some techs hate this 'feature' so much. I base this on (A) the fact that it can be turned off via windows w/a registry hack, and (B) it enables a subnet to communicate machine to machine when a DHCP server is down. Even my network+ instructor hated the concept of APIPA. Know what it is and then either use it or turn it off.

It's been down longer than that

I came home from a weekend on the east coast Sunday and couldn't get online, kept pulling a 169.x IP address. After a call to tech support I was told I had a bad modem and should exchange it on Monday. When I got home with the new modem that afternoon it wouldn't even sync. Hopefully this gets fixed quickly, kinda hard to work from home when you can't VPN into your corporate network.

Edit: Can't spell today

Question

What would happen if you just hard-coded the valid IP address you previously had into the router as a static IP?

it should work but if you have an IP just check when your DHCP lease is up you should be ok till then

That's their normal state...when in doubt, guess.

Re: Question

The cable modem also gets an IP address from DHCP. So, if it has lost its IP and it can't complete DHCP then it will not be able to bridge the traffic. So, in this case, hard coding your IP address into your computer would not work if your modem does not have an IP.

This problem is still occuring or is it resolved? Not much clarification on that aspect...

I love static

This is why true static address should always be option providers offer. This is why I won't touch any dynamic or even sticky service. I don't trust any provider to when it comes to my device configurations. I prefer them to just to keep their circuits and routers up.

This is news?

Years ago when I had @Home, and ATT Broadband both providers had issues with dhcp, and dns so I had two network cards on two different configurations, one on static, another on dhcp.... I ended up using the static configuration very frequently, and that was on top of serious packet loss they said was not a problem....

The hatred comes form administering large private nets, without DHCP, or with DHCP reservations and no leases, etc. It's annoying to get BS arps coming from 169.xx.xx.xx from boxes that some clooless users decides to plug into your network...

Re: I love static

Comcast does offer fixed ip for home offices in lower priced business packages but I think it starts at around $100/month. I looked into it for my wifes office but it didnt seem to offer anything other than a fixed ip for the most part. I am not knowledgeable about dhcp but something tells me a fixed address is no safeguard against dhcp or other large network issues. Comcast is the only show in town and they are better than @home or att were for reliability so I cant be too ungrateful. I did put my modem and router on their own power backup for the inevitable PG&E outages this winter.
