This guide attempts to introduce IPv4 basics, such as IP addresses and Subnet masks.
A "Host"
In computer network theory, a host can be simply defined as a networked device that has an IP Address assigned to it. This could be a desktop, server, phone or router or anything else.
IP Address
This is essentially an ID number assigned to a host. All IPv4 addresses are split into 4 sections called "octets". Each octet contains 8 bits, this means each octet can range from 0 - 255. Much like how a physical address works the IP address intends to make it easy for packets to find you.
192.168.1.1 is an example of what one could look like.
Network and Host portion
IP addresses are split into two different parts
Subnet Mask
A subnet mask is what is used to divide different networks. When we convert to binary a subnet mask will appear as a string of 1's followed by 0's. Example:
11111111.11111111.11111111.11110000 255 .255 .255 .240
