Version 2.1.0

Run up to 256 mixed domains, IPv4/IPv6 addresses, and ASNs in one batch. Results are grouped by type with per-tab CSV export and normalized RDAP/WHOIS fields.

Compute network and broadcast addresses, subnet and wildcard masks, usable host range, host counts, legacy IP class, and dotted-binary network/mask views from any IPv4 CIDR. Plain addresses default to /32; optional shareable ?cidr= query param.
