Cyber Data: IP Address, Bitcoin Address.

The World Wide Web and Bitcoin run on the Internet. Fo a phone number, reverse number apps can (sometimes) provide the identity of the owner/user of that phone number. With the Internet, if you have an IP Address, a lookup app such as www.ip-tracker.org will get you the Internet Service Provider (ISP) but NOT the owner/user of that IP Address. For that detail, privacy laws protect users (including criminal hackers), and a Court Order (Subpoena) served on the ISP is necessary to identify the user (name, address, ...). Be advised, time is of the essence -- there's no law requiring ISP's to save data, and IP Address user information is typically saved for only 180 days.

IP Address

   a. IPv4 format is 111.222.333.444, where each of the 4 groups separated by periods can be 1, 2 or 3 numbers 0 thru 9.

       > Example: 199.7.207.33 with ISP:Responsys, AS Number:AS16474 Responsys Inc. The Autonomous System (AS) number 16474 was assigned to Responsys Inc on 2000-05-01 by the Regional Internet Registry ARIN. The American Registry for Internet Numbers (ARIN) is the Regional Internet Registry for Canada, the United States, and many Caribbean and North Atlantic islands.

       > Some sequences are protected and not available for lookup. They are typicaly used for home or business modem, router and devices on Wifi. Examples: IP address ranges 10.0.0.0 – 10.255.255.255, 172.16.0.0 – 172.31.255.255, 192.168.0.0 – 192.168.255.255 and 224.0.0.0 - 239.255.255.255 are reserved for private internet use and IP lookup for these will not return any results.

   b. IPv6 format is 1111:2222:3333:4444:5555:6666:7777:8888, where each of the 8 groups separated by colons can be four hexadecimal digits e.g. numbers 0 thru 9 or letters a thru f.

       > Example: 2001:0db8:0000:0042:0000:8a2e:0370:7334 with an ISP in Stockholm Sweden.

       > IPv6 address space is so big (3.4×10^38), that every grain of sand on earth (~7.5 x 10^18) could have it's own address -- with plenty remaining for internet devices.

Bitcoin Address

   a. Bitcoin Wallet: A pair of character sequences e.g. Bitcoin Address and Private Key. A public Bitcoin Address is used to Deposit bitcoins to a wallet. A secret Private Key is used to Withdraw bitcoins from a wallet. Be advised, whoever has the Private Key owns the bitcoins. On Exchanges, typically only the Bitcoin Address is shown. Technically the Exchange owns the bitcoins, and there is a "promise to pay" the user of that wallet -- just like Banks "promise to pay" account holders. However, since Bitcoin is a market driven product, like an IRA or 401K, there is no FDIC-like entity as in Banks -- since Bank accounts are NOT market driven.

   b. Bitcoin Address Example: 1BzKkord11NSuGu5FjQAAL3xLQcFm3G3vH

        > Wallet Transactions and Balance on Public Blockchain: https://blockchain.info/address/1BzKkord11NSuGu5FjQAAL3xLQcFm3G3vH

   c. Private Key Example: 5KRTGZmZHVMuzpJ99GjNfCoNeUYUum8kwXoVrx9pA21JSbySvPT

        > Sweeping the Private Key, from a Bitcoin app on a computer or cell phone, will withdraw the wallet balance and send those bitcoins to another wallet on the computer or cell phone.
