Since when do I use 8.8.8.8?

Did comcast just change my router setting, again..

I was just doing some testing for the newly created site where I have restricted access to admin interface by IP.

I could not get in, kept getting my own message no Access - 403.

I've looked at the headers sent in FireBug and Guess what?

X-Forwarded-For:8.8.8.8

I am Comcast customer for a very long time. Did all Comcast customers got switched to this?

Si I went to one of the websites that determines my IP Address:

Your IP: 8.8.8.8?
Proxy: 73.178.223.XX <<< this is my IP
City: mountain view
State/Region: california
Country: us - us flag
ISP: google inc.

What Gives?

WHOIS (ARIN) shows that IP belongs to Comcast:
Comcast IP Services, L.L.C. NJ-CPE-3 (NET-73-178-0-0-1) 73.178.0.0 - 73.178.255.255
Comcast IP Services, L.L.C. CABLE-1 (NET-73-0-0-0-1) 73.0.0.0 - 73.255.255.255

The 8.8.8.8 would be Google (Cloud) servers, they are all over the world.
8.8.8.0/24 Google Inc.
United States

I would see about a tracert lookup and you will probably find that Comcast (like other ISPs') traffic passes through servers you never agreed to be on.

8.8.8.8 is the Google Public DNS server not some kind of proxy

Did you enter in your computer configuration 8.8.8.8 as the IP address of your computer instead of the IP address of your DNS server? In that case you might get such weird results where your outbound IP address seems to proxy for your internal IP address.

X-Forwarded-For:8.8.8.8
...
Your IP: 8.8.8.8?
Proxy: 73.178.223.XX <<< this is my IP

I too am confused by this. Isn't the X-Forwarded-For header supposed to give your "real" IP,* while the proxy--if you're using one--is what shows up in logs as the requesting IP?

Is the question mark part of the original that you're quoting?


* I have never yet figured out what it means when an X-Forwarded-For lists two or more completely different IPs. Or, for that matter, the identical IP twice.
