How would you define IP address?
Answer
IP address or Internet Protocol address is the address of a device attached to
an IP network (TCP/IP network). It is a must for every client, server and
network device to have a unique IP address for each network connection (network
interface). Every IP packet contains a source IP address and a destination IP
address. As a device moves from one network to another, its IP address changes.
Difference between Static and Dynamic IP
Answer
Static IP is also called as permanent address assigned to each device in a
network, whereas Dynamic IP, a temporary address assigned to the device via
DHCP software. IP address assigned to your service by your cable or DSL
Internet provider is typically dynamic IP. In routers and operating systems,

What is Network Address Translation?
Answer

network. It is a dynamic method which is used to minimize Internet connectivity
needs. Network address translation describes the rewriting of the Internet
Protocol (IP) addresses of data packets so that multiple transmissions require
only one IP address.

organizes the network. For instance, it can logically group computers belongs
to the finance department.
Define Address Resolution Protocol.
Answer
Address Resolution Protocol ARP, is responsible for mapping an IP address to
its corresponding physical network address. It is mostly seen on Ethernet
network.
