What are Network Tools?
Working with servers, you keep re-deriving the same things: how many hosts fit in this CIDR, whether an address is private or public. These do the arithmetic and the judgement calls so you don't count binary by hand.
When you need them
- You need to know the host range and count for a CIDR block
- You're checking whether an IP is private, public or reserved
- You need a valid MAC address for a VM or a test
- You want a free port number that won't collide with a known service
