The first three sets of numbers match but not the fourth set.
Could this then just be a coincidence?
GOTCHA! The first three sets being similar means this is likely a Class C network. A Class C network has 254 distinct addresses, from 1 to 254 (0 and
255 are not used. 0 plus 255 = 256, 2 to the 8th power) GUARANTEED that it's this net is owned by the same entity. Net address blocks are typically
owned in Class C chunks, though now that addresses are getting scarce, you can be assigned a subset. They COULD be sub-netted, but this is unlikely.
Each computer in a network has its own complete address, thus on a single class C you could have
220.127.116.11 gateway router
18.104.22.168 Color Printer
22.214.171.124 Jim's PC
126.96.36.199 Mike's PC
188.8.131.52 Fileserver #1
184.108.40.206 last of series
The DNS system would be set up to route any of the numbers 2-254 through the "dot one" router out to the Internet.
I used to manage a dozen Class C nets for where I worked. Each building had its own Class C. The large buildings were running out of addresses by the
time I left because everything from copy machines to printers, telephones, everything had its own IP address.
If you've got the first three, you can look up the network in a variety of sources and see who it belongs to. That would settle whether this is owned
by a utility, qwest, for example, that COULD assign addresses in subnets, or whether the entire Class C was owned by a single entity.
So, whoever has the numbers, just look it up! Like here.
Just type in the Ip in dotted decimal format:
220.127.116.11 It will say who owns it, what the range is, etc. It should be easy to tell if both IPs are owned by the same entity. And if it's
something like: Industrial Light and magic, well....
