ISP numbers - what can they tell you(7 Posts)
Can anyone explain whether an ISP number has any geographic/location significance?
i.e. can one assume
a) that ISP 188.8.131.52 was located near to 184.108.40.206
b) that ISP 220.127.116.11 was activated immediately before 18.104.22.168
c) that ISP 22.214.171.124 may be another computer manufactured/purchased immediately before 126.96.36.199
d) ISP numbers are entirely random.
Many thanks in anticipation
You mean the IP address?
"Can anyone explain whether an ISP number has any geographic/location significance?"
Sometimes..... But not always. It depends on the address and who allocated it.
"that ISP 188.8.131.52 was located near to 184.108.40.206"
Possibly... However there might be multiple computers hiding behind that IP address which could be scattered all over the place.
"220.127.116.11 was activated immediately before 18.104.22.168"
"22.214.171.124 may be another computer manufactured/purchased immediately before 126.96.36.199"
No, the IP address used by a machine has no connection to the date the computer was built, two very different things.
"ISP numbers are entirely random."
No, well not quite, they do have a pattern to them.
It's worth nothing that both of the addresses you give are owned by Yahoo.
It would help if you explained exactly what you're trying to work out, how did you get this addresses?
Sorry, not Yahoo, I think that they below to Inktomi Corporation
Academic whether it says Inktomi or not, it looks to be part of Yahoo! anyway. Large IP address range, with some 16,000 possible different connections (24 * 256) so presumably someone using something like Yahoo! Mail, Yahoo! Answers or whatever, that has perhaps insulted OP.
NetRange: 188.8.131.52 - 184.108.40.206
NetType: Direct Allocation
OrgName: Inktomi Corporation
Address: 701 First Ave
OrgTechName: Netblock Admin
"number has any geographic/location significance?"
At country level, then yes, it is fairly common for that to be identifiable. Any closer than that is less and less likely.
Some services may describe their pool of IP addresses in more detail, so for example, a Cable TV/ISP business might indicate which State and even City, a connection is from. Similarly, in the UK, Virgin Media (cable) may also do the same - it helps the company because they may be able to check down to street level when there is a fault.
With many other UK ISPs, however, using BT's network, the connections are generally put through larger and larger concentrators until they get to the interface (gateway) with the ISP (typically in the London area).
So while some of my ISP (PlusNet) servers are in Sheffield, my connection shows little or nothing about my location, just the PlusNet Gateway used for the connection (at the moment, next hour, next week, it could be via a different gateway system, all in London as far as I know, but different data centres are used to limit the risk of power failure etc).
You can get some details about the IP address info if you visit www.dnsstuff.com but be warned, while I am in N Wales it reports London (fine by me!). (Back to ISP equipment, I assume.)
They are very hit and miss in my experience and if you use a geolocation database service you can get some wild replies.
I have a geolocation plugin installed on one of my blogs.
My ISP is BT, my location seems to alternate between London and Birmingham (which I'm in neither).
Using the same Geo-location service on my work ip address reports Germany (not there either).
However, my parents IP address has very static location and it's in the right place - they are on O2/Be.
Just echoing what Liamsdaddy said- I'm with Talk Talk, used to be with BT, but geolocation software rarely shows my real location. Often they will say that I'm in either Manchester or London when I'm in neither. One even came up with Paris, I wish
