Subnet Calculator
Calculate IPv4 networks, masks, ranges, and usable hosts.
19 tools
Network, DNS, storage, permissions, and troubleshooting utilities for IT work.
IT Tools on Haivix focuses on the small calculations and lookups that interrupt network, server, storage, Linux, and email work. Calculate a CIDR range, inspect DNS or domain registration, decode an IPv4 value, size a TCP window, or check a common port without installing a desktop suite.
Local calculators keep their input in your browser. The DNS and RDAP tools clearly identify the public resolver or registry service that receives a lookup, so you know when a query leaves the page.
