There are two versions of IP
1. IP version 4: offers IP up to 4.2 billion (32 bit size).
2. IP version 6: 128 bit size
IP address is used for identifying the system and provides communication
IP address is of 32 bits divided in four octets
Each Octet is of 8 bits, separated by a (.) dot
IP is a combination of Network ID & Host ID
Uses subnet mask to differentiate Network ID with Host ID Subnet mask acts like a mask between Network ID & the Host ID Numbers range between 0-255.
Class A: 1-126 (Used in LAN/WAN)
Class B: 128 – 191 (Used in LAN/WAN)
Class C: 192 – 223 (Used in LAN/WAN)
Class D: 224 – 239 (Used for Multicasting)
Class E: 240 – 254 (Used for Experimentation & Research)
0.0.0.0 is reserved as Network ID
255.255.255.255 is reserved as Broadcast ID
127.0.0.1 is reserved as Loopback ID
169.254.x.x is known as APIPA (Automatic Private IP Address)
