Fundamentals Of Networking

IP Address:It is an address provided to every computer or nod in network by ISP(Internet Service Provider) to connect to using internet.In VPN(Virtual Private Network ),it may have been provided by server.

Domain Name System (DNS): This allows IP address to be translated to words. It is easier for human being to remember character.
E-mail addresses are also converted by DNS in character or string.

For example, it is much easier for anyone to remember address "facebook.com" than to remember 69.63.189.63.

Dynamic IP Address: One that is not static or other word changing.It is given by your ISP or DHCP(Dynamic Host Configuration Protocol
) Server.
Computer will get this number as it logs on to the network and saves you the trouble of having to know details regarding the specific network configurations.
This number can be assigned to anyone using a dial-up connection, Wireless and High Speed Internet(i.e DSL,TSL Cable) connections.

Static IP Address: One that is fixed and never changes.
Most ISP's can offer to assign a single static IP for Some more rupees(or your currency).

IPv4: It is being used by most devices.However,IPv4 IPs are running out quickly.
IPv4 is limited to 4,294,967,296 IPs.

IPv5: This is an experimental protocol for UNIX based systems. In keeping with standard UNIX release conventions, all odd-numbered versions are considered experimental. It was never intended to be used by the general public.

IPv6: The replacement for IPv4.
The estimated number of unique IPs for IPv6 is (340,282,366,920,938,463,463,374,607,431,768,211,456)(Count how many no. are there???!! lolzz) or Base(2)mentisa(128).
