Study Notes

Nat Network Address Translation (NAT) masks private IPv4 addresses to allow them on the internet.
Loopback address is a way to test TCP stack functionality by pinging your own device.
Link local address is automatically assigned when manual configuration or DHCP failure occurs.
Classful addresses, including Class A, B, and C, had fixed subnet lengths in the first octet, with private addresses falling in Class A, B, and C.
Regional Internet Registries (RIRs) manage IP address assignments, with Ayalna managing the Internet Assigning Number Authority (IANA).
Broadcast domains are layer 2 domains where broadcasts are forwarded to all switches, but do not cross layer 3 boundaries.
Segmentation separates networks into smaller networks to reduce overall network traffic, improve performance, and increase security.
Virtual LANs (VLANs) allow for virtual segmentation when physical segmentation is not practical.
Subnetting in IPv4 networks involves dividing a network into smaller networks by locking in octets beyond the first one.
Increasing the second octet is possible when 255 is reached, allowing for more subnets.
Subnetting can be done on octal boundaries after the first 8, 16, or 24 bits.
