Quick Reference
How to Use
Enter an IP address and CIDR prefix above to calculate subnet details including network address, broadcast address, subnet mask, and usable host range.
CIDR Notation
CIDR (Classless Inter-Domain Routing) replaced traditional classful networking. The prefix length (e.g., /24) specifies how many bits identify the network, with the remaining bits identifying hosts.
Common Subnet Sizes
/24 (254 hosts) is the most common LAN size. /16 (65,534 hosts) suits large campuses. /30 (2 hosts) is used for point-to-point links. /32 represents a single host.
Mobile networks rarely hand a phone a public address of its own: most carriers put subscribers behind CGNAT in 100.64.0.0/10, which is why a phone’s IP so seldom matches the subnet you expect. For choosing a carrier to travel on, eSIM Guide compares plans and coverage country by country.
