WHAT IS A IP ADDRESS

 

(Internet Protocol) address 


device used by routers, to select best path from source to destination, across networks and inter networks

 

network layer address, consisting of NETWORK portion, and HOST portion

 

logical address,assigned in software by network administrator

 

part of a hierarchical ‘numbering scheme’ – unique, for reliable routing

 

may be assigned to a host pc, or router port

 

TYPES OF ADDRESS

 

Static address

 

Dynamic address

 

STATIC- IP ADDRESS

 

 

Static  address 

 

1.manually input by network administrator

 

2.manageable for small networks

 

3.requires careful checks to avoid duplication

 

DYNAMIC-IP ADDRESS

 

 

Dynamic address 


examples – BOOTP DHCP

 

assigned by server when host boots

 

derived automatically from a range of addresses

 

duration of ‘lease’ negotiated, then address released back to server

 

 

CLASS OF IP ADDRESS

 

 

A Class  – large organizations  governments 


Class B – medium sized organizations 


C Class  – small organizations

 

CLASS – A

 

1st octet = network address, octets 2-4 = host address

 

1st bits of 1st octet set to 0

 

up to (2^24 – 2) host addresses (16.8M)

 

 

CLASS-A  ADDRESS

 

124.224.224.100

01111100 11100000 11100000 01100100

 

CLASS – B

 

1st 2 octets = network address, octets 3-4 = host address

 

1st 2 bits of 1st octet set to 10

 

up to (2^16 – 2) host addresses (65534)

 

CLASS – B  ADDRESS

129.224.224.100

10000001 11100000 11100000 01100100

 

 

CLASS – C

 

1st 3 octets = network address, octet 4 = host address

 

1st 3 bits of 1st octet set to 110

 

up to (2^8 – 2) host addresses (254)

 

CLASS – C  ADDRESS

What is loopback address?

On Linux the loopback interface is commonly know lo or lo0. The corresponding hostname for this interface is called local host.The loopback address is the address used to access itself. The v4  127.0.0.1 as the loopback address with the 255.0.0.0 subnet mask. A loopback interface is also known as a virtual ,which does not associate with hardware interface.

IP ADDRESS test  software without installing a  server or  virtual network  for best option to check a hardware of n.i.c (network interface card,) and without plug a cable  having to physically connect the machine to a TCP network. A good example of this is to access the server
