subnet

Definitions

1. A logical subdivision of an IP network, created by applying a subnet mask to partition a larger address space into smaller, isolated segments. Subnetting enables network segmentation for security (isolating databases from web servers), efficient address allocation, and traffic management.

   In plain English: A smaller network carved out of a bigger one — like dividing an office building into separate floors that can control who visits.

   Example: We put the production database in a private subnet with no internet gateway, accessible only from the application subnet via security group rules.
