Just because you can't resolve an IP address does not mean that it does
not exist. There is no rule that says IP address *have* to have dns
resolution. That IP is a valid address, so it is very possible that it
does exist. Whois info for it says that its from China, I suspect you
will be seeing lots of these, its fairly normal noise.
