Frequently Asked Questions
What is an IP address range?
An IP address range is the set of all IP addresses between a starting and ending address within a subnet. For example, 192.168.1.0/24 has a range from 192.168.1.0 (network) to 192.168.1.255 (broadcast), with usable hosts 192.168.1.1 to 192.168.1.254.
What is the difference between total addresses and usable hosts?
Total addresses include the network address and broadcast address. Usable hosts exclude those two reserved addresses. A /24 subnet has 256 total addresses but only 254 usable hosts.
