Who or what is this IP address?

[Donomni]

So, Malwarebytes keeps flagging this one IP address all the ding-dong time, and after having a full Malware scan and a full AVG scan, I *still* have no idea who or what is trying to talk to my computer, just that the IP is centered in China.

I don't remember any rules about dubious IP addresses, so here it is: 121.10.81.27

I'm not sure if anyone can help me with this, but it's getting kinda worrying at this point.

Any ideas, folks?

It's a Chinese IP registered to http://27.81.10.121.broad.zj.gd.dynamic.163data.com.cn/

http://ip-lookup.net/neighborhood.popup.php?ip=121.10.81.27 shows it's 'family' all being registered to the same source.

The WHOIS data responds no core details; it doesn't have recorded who the owner of the IP is.

here's everything else you might want to sift through for your own enjoyment:

Hope I helped!

Thanks for the info.

Although I'm not sure what I could use it for yet.

Still wonder how I got this IP's attention in the first place. The IP blocks say my computer is blocking incoming and outgoing data. ...really doesn't make me want to type anything like my various account passwords. I wonder if there's a more surefire way to block certain IPs.

Again, thanks for the IP info. I'll keep it on hand in case I need it.

[Grandmaster_Skweeb]

You could block all incoming and outgoing traffic to that IP on the routing layer, I.e. router's firewall. Mostly in case there are other computers/ devices that are also being talked to by that address. I'd also set up logging to have a record of how often the chatter occurs.

If nothing else tell your ISP that you're getting odd chatter from an IP address in Asia that might need some monitoring.

I did IP search for 121.10.81.27 in IP-Details.com (http://www.ip-details.com/) and found the following information:
Country : CHINA
Internet Service Provider : CHINANET-GD, CHINANET GUANGDONG PROVINCE NETWORK
IP Location : No.31 ,jingrong street,beijing, 100032

You can block an Incoming and Outgoing traffic to that Ip address by configuring your Router Firewall.

Hey wow this thread is super old and has been inactive for nearly a year, so I'm gonna go ahead and close it.

InJun, welcome to the forums! Please bear in mind that we do have a rule about bumping threads that haven't been active for more than a month, and while there is some wiggle room, this thread really didn't have any wiggle left in it.

Don't feel bad, though. It's a common rookie mistake and I'm sure you'll learn from it!
