Hello everyone.

I have what I'm sure is a noob question, but I was just wondering what the IP address 172.27.35.1 is used for. I noticed with ipconfig and PG2 that my computer is connected to it, but when I did a google search, I only got 31 hits ( a sign that maybe it's not a typical internal IP like 192.168.0.0) Every page in my Google search mentioned Ooma VOIP service which I do not have. What could this be? Should I be concerned?

Thanks in advance for suggestions

P.S. Hijackthis and malwarebytes scans turned up nothing of concern

Can you post a picture of what/where you are seeing this?

And who told you HJT was clean?

I am unable to post a picture. But any program that shows network connections, such as ipconfig/all or PG2 will show this IP. My HJT log shows nothing new and all entries are accounted for.

172.27.35.1 address belongs to 172.16.0.0 - 172.31.255.255 range of private IP addresses:
http://whois.domaintools.com/172.27.35.1

More info: http://www.pcmag.com/encyclopedia_term/0,2...;i=58632,00.asp

An IP address within three ranges of numbers that are set aside for the computers in local networks. Typically assigned to the machines by a DHCP server, these private addresses are not routed over the Internet. In order to gain access to the Internet, the private addresses are converted to a public IP address that is exposed to the Internet by a network address translation (NAT) service.


In plain words, nothing to worry about.

ok...ipconfig /all shows alot of info can you MAYBE narrow it down a little to what that IP address pointing to? IP address? Default gateway? DHCP server? DNS Servers?

Does your start with 192?

Address starting with 192 would be your router.
Any device, which connects to the internet and is behind the router has to have own IP too.
Since they're behind the router, forming so called intranet, they can't be accessed from the public internet.
Thus, they can't have public IP and they're assigned with some IP from private IP range.

Its a private address as Broni has already said above. You say that your computer connects to it. That means you are directly connected to a cabled LAN that provides you with internet service.

That is your IP address and it is nothing to worry about.

Just out of curiosity, what is the make and model of your router?

OK, it turned out to be the router on the home network. I would have known but it's an in-house network that my roommate set up before i moved in :thumbsup:
