Mumbai cops try to gather a listing of all IP address on CD’s

Filed under: My Thoughts — Suramya @ 1:37 PM

Here’s more proof that the Mumbai police has no clue about computers and computer networks. In this latest insanity they have decided to speed up cyber crime investigations by creating a database of all the internet protocol (IP) addresses across the cosmopolitan which will supposedly help in detecting the details of an Internet user in a few minutes. So far 6 ISP’s have ‘cooperated’ by giving them a CD of IP addresses mapped to physical addresses of all their subscribers.

This shows that they have never heard of a little thing called DHCP (Dynamic Host Configuration Protocol) that most ISP’s use to dynamically allocate IP addresses to their subscribers everytime they logon.

I know for a fact that BSNL (a big Indian ISP) gives out a new IP address every 24 hours regardless of weather you have restarted your modem or not. Airtel allocates a new IP address everytime the DSL modem is restarted and I am sure the same is the case with all other ISP’s.

This would only work if they cops have a direct live access to all records at all the ISP’s (Which has huge privacy implications) or the ISP’s have to start handing out static IP’s. Otherwise any information no matter how frequently updated will be outdated. All a person has to do to avoid identification is to use a proxy, or use one of the open wireless access points or just reboot the DSL router and they have a new IP address that is not mapped to their address. The IP might even be mapped to another subscriber’s address.

This is a step in the wrong direction. If this is not stopped then the next step will be direct access to the ISP DB’s and monitoring of what everyone does online and soon we just might have the “great firewall of India” in addition to the “great firewall of China”. Already idiots are clamoring for banning of various sites that ‘offended’ them.

  1. how i can find out details from ip address

  2. Well it depends on what you mean by details. You can’t really get personally identifying information about an IP address unless you work for that ISP and have access to their logs.

    For general information you can use an IP to Location conversion to figure out aprox where an IP is located. One of the sites I found for this is According to that site this IP is an IP based in Bombay/Mumbai and is owned by “INDIA’S PREMEIR BROADBAND AND IPTV SERVICES MUMBAI. (PACENET-INDIA.COM)”

    Other than that there is not a lot of info that you can get publicly. Why are you so interested?

    Oh, and your IP (The one used to post the comment) is based in Pune, MAHARASHTRA and is owned by NIB (NATIONAL INTERNET BACKBONE)
