Study Notes

IPv4 Address

An IPv4 address is represented by 4 numbers separated by dots, each in the range of 0-255.
These numbers need to be converted to 0 and 1 for computers to understand.
An example of an IPv4 address is 189.123.123.90.

Static IP Address

Static IP addresses do not change with time.
They are considered permanent internet addresses.
DNS servers primarily use static IP addresses.
A device needs a static IP address to send packets to the internet (WAN).

Subnet

A subnet is a logical grouping of connected network devices.
Devices on a subnet are typically located physically close together on a LAN.
Subnets are used to divide networks into logical segments for better administration.
Properly implemented subnets enhance network performance and security.
Devices on a subnet share a contiguous group of IP address numbers.
A subnet is essentially a smaller network within a larger network.
Subnetting improves network efficiency by reducing the distance network traffic needs to travel, minimizing unnecessary router hops.
Subnetting defines which bits of the IP address belong to the network portion (subnet) and which belong to the host.
A subnet mask, with a "1" indicating network bits, demarcates network and host portions of IP address.
