SOME IMPORTANT PROTOCOL AND THEIR WORK
SOME IMPORTANT PROTOCOL AND THEIR WORK
ICMP (Internet Control message Protocol) - For connection troubleshooting.
ARP (Address Resolution Protocol) Used to resolve IP to MAC address.
RARP( Reverse Address Resolution Protocol) Used to resolve MAC to IP.
DHCP( Dynamic Host Configuration Protocol ) Used to provide automatic IP address
HTTP (Hyper Text Transfer Protocol ) Used to access web pages from browsers.
SMB ( Service Message Block ) Used to share resources for windows PCs.

IP ADDRESS
IP ADDRESS
IP address is a logical address which is assigned to networking devices for their identity. Using IP address we access resources from one device to another device.
There are two version of IP address.
1--IP version 4
2--IP version 6
IP VERSION 4--
It is a 32 bit logical address written in dotted decimal. It is used to identify devices in a network . It has two part network ID and Host ID . Network ID indicates an unique ID for network and Host ID indicates device ID in network.
There are five classes in IPv4 according to size of network and purpose.
Class A- 1.0.0.0 - 126.255.255.255
- In A class IP, 8bit is for NID and 24 bit for Host ID.
- Default Subnet mask for this is 255.0.0.0
- Total Subnet in A Class IP is 27-2=126
- Host per Subnet = 224-2 = 16777214
- Private IP - 10.0.0.0-10.255.255.255
Class B- 128.0.0.0 - 191.255.255.255
- In B class IP 16bit for NID and 16 bit for Host ID.
- Default Subnet mask for this is 255.255.0.0
- Total Subnet in B Class IP is 214 -2=16382
- Host per Subnet = 216 -2=65534
- Private IP - 172.16.0.0 - 172.31.255.255
Class C- 192.0.0.0 to 223.255.255.255
- In C class IP 24bit is for NID and 8 bit for Host ID .
- Default Subnet mask is 255.255.255.0
- Total Subnet in C class IP is 221 -2= 2097152
- Host per Subnet = 28-2=254
- Private IP - 192.168.0.0- 192.168.255.255
Class D- 224.0.0.0- 239.255.255.255
D class is reserved for multicasting
Class E- 240.0.0.0 - 255.255.255.255
E class is reserved for research
Special IP addresses...
APIPA (Automatic Private Internet Protocol Address ) -----
It is assigned to devices Automatically when no DHCP server is active in network and static IP address has not been configured too. APIPA ranges from 169.254.0.0 to 169.254.255.255.
Loopback Address- Loopback address is for Loopback test of devices. Reserved address is 127.0.0.1
Default Broadcast Address- 255.255.255.255
Private IP -
Private IP address is free to use. We can use this IP without any permission of ISP. Private can only be routed in private Network . We can share and access resources in private network only.We can connect our private computer to public network using a router or Server . We will have to configure NAT on Server or Router.
There are two type of IP addresses are used.
1- Class full address- When we use default subnet mask with IP address , This is known as Class full address. Class A, Class B and Class C addresses are class full addresses.
2- Class less addresses- When we use subnetted Address and new subnet mask . We do not follow Class . This is known as Class less addresses.
Follow this table to know block size and subnet mask.
