About this plugin

Subnet planning looks straightforward on paper, but hand-calculating network addresses, broadcast ranges, wildcard masks, and usable host counts is tedious and error-prone. xby-subnet-calculator turns these repetitive arithmetic steps into conversational tools that return the answer right in chat, eliminating the need to jump between browser tabs and online calculators.

Built on the Model Context Protocol, the plugin covers the full spectrum of IPv4 subnet work: deriving subnet parameters from a base IP and host count, looking up network details from an IP and mask, generating OSPF wildcard masks, verifying whether a given IP falls inside a target subnet, and retrieving the Nth usable address in any prefix. A single conversation yields a complete network parameter sheet.

If your daily workflow involves VLAN design, OSPF area configuration, IP conflict triage, or networking certification prep, this plugin lets you skip the arithmetic and focus on the architecture decisions that actually matter.

Use Cases

  • Quickly derive subnet parameters, network address, and broadcast range from a required host count
  • Generate OSPF wildcard masks and verify whether an IP belongs to a target subnet
  • Look up the Nth usable IP address in any prefix without manual counting

Best For

  • Network administrators who handle VLAN design and IP range allocation daily
  • Network engineers who use wildcard masks repeatedly in OSPF area configuration
  • Learners preparing for CCNA, HCIA, or similar networking certifications
