Answer 1

You can get thier address if they have sent you an email from their computer / Network. If you go to your mail and view headers you can get the senders original public address. I did this a few times when i was getting weird email and i took the ip address and put it into "Visual Trace Route" and found out were they were coming from. This will not however give you any kind of access to thier computer when you get it.

IP = Internet Protocol, it's the "language" used on the Internet for different devices to communicate. Every device connected to the Internet needs an address. Hence IP address.

When you try to connect to something on the Internet, say yahoo.com you are actually connecting to yahoo's IP address. Every packet you send has a source IP address (you) and a destination IP address. The source address is used by the destination device to determine where to send the packet back to. If you don't know the IP address, only the FQDN (fully qualified domain name), then your computer uses something called Domain Name Service (DNS) to convert the name (yahoo.com) to an IP address (216.109.112.135 for yahoo).

To get the IP address of a Windows PC, use the command line interface (start - run - cmd) at the prompt type "ipconfig", this will tell you your IP address.

You can't communicate on the Internet without an IP address, basically what you pay for with an Internet service provider is the rental of a legal IP address. There are so many legit IP addresses in the world, they are a valuable commodity. You can't just make up an IP address an use it.

What Are IP Addresses?

An IP address is a 32-bit identifier assigned to a host that uses the Internet Protocol. The IP address is represented by four octets (8-bit fields). In decimal form, an IP address consists of four fields separated by dots, where each field contains a value in the range 0 - 255. This is called dotted decimal notation.

Each host ID must be unique within a given network, and each network number must be unique within a given internet. Host IDs are assigned by the network administrator. The network number is assigned by the inter-network administrator. For a public network on the Internet, you must obtain a network number assigned by the Network Information Center (NIC).

An IP address consists of two parts. The first part of the address, called the network number, identifies a network on the internet; the remainder, called the host ID, identifies an individual host on that network. Historically, three classes of IP addresses have been defined:

* Class A--Only the first field identifies the network, and the number in the first field must be in the range 1 - 126 (127 is reserved for loopback). Class A networks are very large. Host numbers 0.0.0 and 255.255.255 are reserved, and one octet is reserved for other purposes, so there can be almost 17 million (224-2) hosts in a class A network. The 126 class A network numbers have been allocated.

Example: 26.4.0.1, for host 4.0.1 on net number 26.

* Class B--The first two fields identify the network, and the number in the first field must be in the range 128 - 191. Class B networks are large. Host numbers 0.0 and 255.255 are reserved, so there can be up to 65,534 (216-2) hosts in a class B network. Most of the 16,382 class B addresses have been allocated.

Example: 128.89.0.26, for host 0.26 on net 128.89.

* Class C--The first three fields identify the network, and the number in the first field must be in the range 192 - 223. (The range 224 - 255 is reserved for classes D and E, for experimental work.) Class C networks are relatively small. Host numbers 0 and 255 are reserved, so there can be up to 254 (28-2) hosts in a class C network. Most LANs are class C networks. There can be over 2 million class C networks in an internet.

Example: 192.15.28.16, for host 16 on net 192.15.28.

Answer 4

IP = Internet Protocol

An IP address is a unique address for a computer or other network device on the Internet.

This link will show you your IP address ...

Answer 5

It is the network address of any equipment connected to a network, a bit like a phone number for computer equipment. Unless you sit at someone's computer you can't get their address.
