Service assignments on a port number

Network Ports API
The official IANA Service Name and Transport Protocol Port Number registry as an API — 12,500+ TCP, UDP, SCTP and DCCP port assignments. Look up what service runs on a port (e.g. 443 → https), find which port(s) a named service uses (e.g. ssh → 22), and search the registry by service or description. A handy reference for networking, DevOps, security and firewall tooling.

TLD (Top-Level Domain) API
Every top-level domain in the IANA root zone as an API — the authoritative list a registrar, domain validator or analytics tool needs. For each TLD: whether it is a country-code TLD (ccTLD), a generic TLD (gTLD) or an internationalized (IDN) domain, its A-label, its Unicode form (e.g. xn--p1ai resolves to .рф) and, for ccTLDs, the country it belongs to. Validate a TLD or whole domain, find a country's ccTLD, filter by type, search, or list the entire root zone. Sourced from IANA's official tlds-alpha-by-domain.txt and served from memory — always fast.

Time Zones API
Every IANA time zone with its coordinates and country, enriched in real time with the current UTC offset, abbreviation, DST status and local time (computed from the system ICU time-zone database — always up to date, no key). Look up a zone by name, list all zones for a country, search zones by name, or find the nearest IANA zones to any latitude/longitude. 418 zones across 247 countries/territories. Ideal for scheduling, calendars, logistics, geo apps and any feature that needs to map a place or coordinate to the right time zone and current local time.

IP Protocol Numbers API
The IANA "Assigned Internet Protocol Numbers" registry as an API — the 8-bit value carried in the IPv4 Protocol field (and IPv6 Next Header) that identifies the encapsulated protocol. Resolve any number to its protocol (e.g. 6 → TCP, 17 → UDP, 1 → ICMP, 47 → GRE, 50 → ESP, 58 → IPv6-ICMP, 89 → OSPF, 132 → SCTP), look up by keyword, search by name, or list all 151 assigned protocols — each with its keyword, full name, IPv6-extension-header flag and defining RFC. Ideal for packet/firewall tooling, network analysis, NetFlow/IPFIX decoders and protocol documentation. (Distinct from transport-layer service port numbers.)

URI Schemes API
The IANA Uniform Resource Identifier (URI) Schemes registry as an API — all 413 registered schemes (http, https, mailto, tel, ftp, ssh, magnet, bitcoin, geo, did, …). Look up any scheme to get its description, registration status (Permanent, Provisional or Historical) and defining reference; search by name or description; or list all schemes filtered by status. Ideal for URL parsers and validators, link handlers, deep-linking, security allow-lists and developer tooling that needs to recognise or vet URI schemes.
