What is an IP address?
Every device connected to the public Internet is assigned a unique number known as
an Internet Protocol (IP) address. IP addresses consist of four numbers separated by
periods (also called a 'dotted-quad') and look something like 127.0.0.1.
In computer networking, an Internet Protocol (IP) address consists of a numerical
identification (logical address) that network management assigns to devices
participating in a computer network utilizing the Internet Protocol for communication
between its nodes.[1] Although computers store IP addresses as binary numbers,
they often display them in more human-readable notations, such as 192.168.100.1
(for IPv4), and 2001:db8:0:1234:0:567:1:1 (for IPv6). The role of the IP address has
been characterized as follows: "A name indicates what we seek. An address indicates
where it is. A route indicates how to get there." [2]
What is subnet Mask ?
A subnet (short for "subnetwork") is an identifiably separate part of an organization's
network. Typically, a subnet may represent all the machines at one geographic location,
in one building, or on the same local area network (LAN). Having an organization's
network divided into subnets allows it to be connected to the Internet with a single
shared network address. Without subnets, an organization could get multiple
connections to the Internet, one for each of its physically separate subnetworks,
but this would require an unnecessary use of the limited number of network numbers
the Internet has to assign. It would also require that
Internet routing tables on gateways outside the organization would need to know
about and have to manage routing that could and should be handled within an
organization.
What is ARP? What is ARP Cache Poisoning?
Address Resolution Protocol (ARP) is a protocol for mapping an Internet Protocol address
(IP address) to a physical machine address that is recognized in the local network.
For example, in IP Version 4, the most common level of IP in use today, an address is
32 bits long. In an Ethernet local area network, however, addresses for attached
devices are 48 bits long. (The physical machine address is also known as a Media
Access Control or MAC address.) A table, usually called the ARP cache, is used to
maintain a correlation between each MAC address and its corresponding IP address.
ARP provides the protocol rules for making this
correlation and providing address conversion in both directions.
