who publishes it

Every fact here about an address came out of a file somebody else published.

What an address is registered as

The delegation chain, top down, and the routing table's view of who announces it. Registrations: facts their holders filed about their own resources.

  • IANA IPv4 Address Space Registry IANA

    Which /8 an IPv4 address falls in, and the name that block was delegated to — a registry for most of the space, and for the legacy blocks the company it went to in the 1980s and 90s.

  • IANA IPv6 Global Unicast Address Assignments IANA

    The same for IPv6: the block an address falls in, and the registry it was delegated to.

  • IANA IPv4 Special-Purpose Address Registry IANA

    That an address is reserved rather than delegated to anybody, and the RFC that reserved it.

  • IANA IPv6 Special-Purpose Address Registry IANA

    The same for IPv6.

  • delegated-afrinic-extended-latest AFRINIC

    Ranges delegated in the African region: the country each is registered in, its status, and when.

  • delegated-apnic-extended-latest APNIC

    The same, for the Asia-Pacific region.

  • delegated-arin-extended-latest ARIN

    The same, for Canada, the United States and parts of the Caribbean.

  • delegated-lacnic-extended-latest LACNIC

    The same, for Latin America and the Caribbean.

  • delegated-ripencc-extended-latest RIPE NCC

    The same, for Europe, the Middle East and Central Asia.

  • ip2asn-combined iptoasn.com

    The AS announcing an address and its name, which is the closest thing to a holder's name published in bulk — and a country for a range that is announced but not delegated. Derived from the routing table rather than from a registry.

  • AS Organizations Dataset CAIDA

    Who is behind an AS number, in words rather than as a handle. Parsed out of the RIRs' own whois, which is where a holder's name lives — the delegated files identify them by handle on purpose. It reaches most of the routing table, including the long tail nothing else names.

    The CAIDA AS Organizations Dataset — https://www.caida.org/catalog/datasets/as-organizations

  • PeeringDB network records PeeringDB

    The same question, answered by the operators themselves: the name a network is listed under and what kind of network it says it is. It has about a third of the AS numbers in the routing table, which is most of the traffic and not most of the names, so it is preferred where it answers and CAIDA's mapping fills in the rest.

What a database guesses about it

Estimates rather than registrations, inferred from latency, traceroutes, whois text and reports. They are wrong often enough that the report labels them, keeps them in their own fields, and never lets one become the country a range is registered in.

This site or product includes IP2Location LITE data available from https://lite.ip2location.com.

  • IP2Location LITE DB11 IP2Location

    An estimated country, region, city, coordinates, postcode and time zone — at a /24 at best, so the coordinates are the middle of a range rather than of anyone on it.

  • IP2Proxy LITE PX12 IP2Location

    Whether an address is listed as a proxy, what kind, and what it scores. Most addresses are not listed, which is not the same as being listed as not a proxy.

Names

Not about addresses at all: what the report calls the things the sources above spell in codes.

  • CLDR Unicode

    The English names behind the ISO 3166 country codes the registries publish. Generated once through Intl.DisplayNames and compiled in as src/countries.csv, so a name is never a lookup that can fail.
