I was reading an article about home configuration and it mentioned that when configuring the router, if prompted to enter you ISPs ip address and you wouldn't know it, to enter 4.1.1.1 or 4.2.2.2. I have been searching online but did not find anything about this addresses.

I cannot ping this IP address from my workstation at work, neither I can trace.

So the need to know what servers they point to in the ominous internet cloud is eating my brain.

Thank you in advance for any responses.

but 4.2.2.2 looks like it belongs to vnsc-bak.sys.gtei.net

the other one doesn't appear to be listed in DNS any where.

So what are you saying?

Level 3 Communications Inc is not a government entity? I don't know. Just Googled around a bit and that is what kept coming up.

It does not however answer the more important question of why his router install instructions would have him put those IP's in if he didn't know the real one... Gov't conspiracy perhaps? hmmm...

Originally the address starting at zero to the start of the 10.0.0.0 network were asigned to entities that were either under government contract or actual govenment entities. So 4.1.1.1 could literally be anything they decided to make it.

With all the IP sharing going on I'm not sure if the original rules still apply. But most probably its behind a firewall.
