Study Notes

IPv4 and IPv6

IPv4 (IP version 4) is the standard protocol for most network communication.
IPv6 (IP version 6) is a newer version with significantly more addresses than IPv4.
Most modern operating systems support both IPv4 and IPv6.

IPv4 Addresses

IPv4 addresses are four sets of numbers separated by periods (e.g., 192.168.1.131).
Each set of numbers (octet) represents an 8-bit segment or one byte.
An IPv4 address has 32 total bits or 4 bytes.
The maximum value for each octet is 255.
IPv4 addresses are in decimal format, but can be presented as binary.

IPv6 Addresses

IPv6 addresses are 128 bits long, enabling a vastly larger address space.
IPv6 addresses are represented in hexadecimal format, with colons separating groups of 16 bits (e.g., FE80::5D18:652:CFFD:8F52).
Each group in an IPv6 address is 16 bits (two bytes or two octets).

IP Address Assignment

Every device on a network needs a unique IP address.
An IP address and a subnet mask are required for proper assignment.
The subnet mask helps determine the local network segment the device belongs to.
Example subnet mask: 255.255.255.0

Default Gateway

A default gateway is needed for communication outside the local network.
It's the IP address of a router.
Example default gateway: 192.168.1.1

Domain Name System (DNS)

DNS translates human-readable domain names (e.g., www.google.com) into IP addresses.
This allows users to access websites without manually entering IP addresses.
DNS servers are crucial for network communication.
Multiple DNS servers (e.g., 8.8.8.8 and 8.8.4.4) can be configured for redundancy.
