List every IP address in a subnet block. Enter a network address and CIDR prefix - usable hosts, network and broadcast addresses are highlighted.
Enter a network address and prefix to list all IPs
This tool lists every IP address in a CIDR block - from the network address through every usable host to the broadcast address. Enter any valid IPv4 network in CIDR notation (e.g. 10.0.0.0/8 or 192.168.1.0/24) to see the complete range with host count, subnet mask, and paginated IP list.
For small subnets (/24 and smaller, up to 256 IPs) the full list renders instantly. Ranges up to /16 (65,536 IPs) are paginated at 256 per page. Any range can be exported as a CSV file regardless of size.
CIDR (Classless Inter-Domain Routing) notation combines an IP address and a prefix length into a single expression - for example, 192.168.0.0/24 means the network at 192.168.0.0 with a 24-bit prefix, covering 256 addresses (254 usable hosts). The prefix length determines how many addresses are in the block: /24 = 256, /23 = 512, /22 = 1024, and so on.
