IP addressing

For any computer to be able to communicate on TCP/IP network, it requires an IP address. This IP address can either be set statically or it can be obtained from our ISP. Any TCP/IP address is a combination of network part of address, plus host part of address along with a subnet mask. An example of such an address is 192.168.1.74 / 255.255.255.0. This is an IPv4 address. Its subnet mask is 255.255.255.0, which tells that the network part of IP address is 192.168.1 and host part of IP address is 74. Netmask defines a range of IP addresses that we can assign to any specific network address. Today we have two versions of IP addressing. One is IPv4 and the other is IPv6.
