What is Subnetting?
Subnetting is the practice of dividing a larger IP network into smaller, logically separated sub-networks (subnets) by borrowing bits from the host portion of…
CIDR Notation Explained
CIDR (Classless Inter-Domain Routing) notation expresses an IP address’s network prefix length as a suffix like /24, meaning the first 24 bits identify the net…
What is a Default Gateway?

What is a Network Gateway?

What is a Broadcast Domain?
A broadcast domain is the set of devices that all receive a broadcast frame sent by any one member of the group — every host in the same broadcast domain gets…
What is a Subnet Mask?
A subnet mask is a 32-bit value paired with an IPv4 address that tells a device which bits of the address identify the network and which bits identify the spec…
