Internal IP Address

The host network address within an IP address is reserved for internal use.

Subnetting

Subnetting divides a virtual network into smaller, more manageable sub-networks.

Availability Zones

Resources in a virtual network can be distributed across different availability zones for higher availability and resilience.

Usable IP Addresses in /24 Subnet

A /24 subnet has 256 total addresses, but after accounting for network and broadcast addresses, 254 IP addresses remain usable.

Study Notes

IP Addresses

The part of the IP address reserved for internal use is specified in RFC 1918.
RFC 1918 reserves IP addresses for internal use to avoid conflicts with public IP addresses.

Virtual Networks

Subnetting in a virtual network refers to the process of dividing a large network into smaller, more manageable sub-networks.
Resources can be placed in different availability zones in a virtual network.

Subnet Sizing

A /24 subnet has 256 total IP addresses, but only 254 are usable because the first and last IP addresses are reserved.

Azure Virtual Networks

In Azure, virtual networks are isolated from each other, and each virtual network can have its own DNS server.
Virtual networks in Azure can be configured to use custom IP addresses.
