MAC Vendor API

healthy 4,033 Subscribers

Identify the manufacturer behind any MAC address. Look up a MAC or OUI to get the assigned vendor, its short name and the exact assignment block (/24, /28 or /36) using the official IEEE registry, search the registry by vendor name to find all of a company’s OUIs, or generate random valid test MAC addresses for a given vendor. MAC addresses are accepted in every common format — colon, hyphen, dot or bare hex — and bare OUIs work too. Built on the open IEEE OUI dataset (~57,000 assignments) and served entirely in-memory, so responses are instant and the service is always available. Ideal for network scanning and monitoring, IoT and device identification, security and asset inventory, NAC and devops tooling.

Subnet API

A fast, fully-local IP and subnet calculator: validate IPv4 and IPv6 addresses with type classification (private, public, loopback, link-local, multicast, CGNAT or reserved), compute CIDR subnet details (network, netmask, wildcard, broadcast, first and last host, total addresses and usable hosts, with IPv6 network and range size), check whether an address falls inside a CIDR block, and convert addresses (IPv4 to integer, hex and binary; IPv6 expand and compress). Every endpoint accepts input via the query string or the request body. Pure server-side compute, no third-party upstream, so responses are instant and always available. Ideal for devops, network automation, IPAM, firewall and ACL tooling and cloud infrastructure.

IP Geolocation API

Geolocate any IPv4 or IPv6 address — country, region, city, postal code, latitude/longitude, timezone, calling code, currency and network details (ASN, ISP, organization). Look up any address or detect the caller's own public IP.

Astronomy API

A fast, fully-local astronomy and ephemeris engine: compute the equatorial (right-ascension/declination) and horizontal (azimuth/altitude) positions of the Sun, Moon and all planets for any observer and moment, get precise rise, set and transit (culmination) times for any body, read detailed lunar state (phase angle, named phase, illuminated fraction, apparent magnitude, geocentric distance, age since the last new moon and the dates of the next new/first-quarter/full/last-quarter moons), and list the exact equinoxes and solstices of any year. Every endpoint accepts input via the query string or the request body. Pure server-side computation (no third-party upstream), so responses are instant and always available. Ideal for weather and tide apps, astrophotography planners, calendars, solar/energy tools, Islamic and lunar calendars, and education.

Geohash API

Work with geohashes through a fast, fully-local API. Encode a latitude/longitude pair into a geohash at any precision (1–12), decode a geohash back to its centre coordinates with the exact bounding box and error margins, list the eight neighbouring geohash cells (north, north-east, east and so on), or get the bounding box, centre and dimensions of a cell. Geohashes turn coordinates into short sortable strings that are perfect for spatial indexing, proximity grouping and map tiling. Pure server-side computation with no third-party upstream, so responses are instant and the service is always available. Ideal for geospatial indexing and search, proximity and nearby queries, map tiles and clustering, IoT and fleet tracking, and location bucketing in databases.
