IP address planning utility for designing and validating IPv4 and IPv6 subnet allocations across telecom network segments — RAN, core, transport, OAM, and roaming interconnects.
IPv4 subnet calculators derive network address, broadcast, host range, and usable count from a CIDR prefix — essential for clean IPAM in mobile core, RAN backhaul, and security zones.
The calculator applies binary mask operations per RFC 1878 for IPv4 and RFC 4291 for IPv6, computing all subnet properties and generating a summary table for documentation.
Built on 3GPP Technical Specifications, ensuring accuracy for production deployments and security audits.
Calculations specifically designed to identify protocol vulnerabilities and signaling misconfigurations.
Core skill for telecom IP network engineers. Proper subnet design separates RAN management, user plane, and OAM traffic, enabling access control lists and routing policy enforcement.

10.44.16.0/22 → mask 255.255.252.0, addresses 10.44.16.0–10.44.19.255, 1022 usable hosts. That block can seed multiple /26 eNodeB loops with room for growth.
IPv4 only in this tool path. Does not replace IPAM conflict detection across VRFs or public/private overlapping designs.
A /24 has 256 addresses; typically 254 usable hosts after network and broadcast. Some cloud/P2P links may reserve additional addresses.
CIDR appends prefix length to an IP (e.g., 10.10.0.0/22), defining the network mask and host range without legacy Class A/B/C assumptions.
RAN/core IP plans, GTP pools, Diameter host addressing, and LI tap networks need deterministic ranges that match firewalls and IPAM — calculators reduce off-by-one errors in change windows.
