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
126.96.36.199 gateway router
188.8.131.52 Color Printer
184.108.40.206 Jim's PC
220.127.116.11 Mike's PC
18.104.22.168 Fileserver #1
22.214.171.124 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:
126.96.36.199 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....
