How does our IP Intelligence compare?
51Degrees offers an IP Intelligence service that's every bit as accurate as other leading providers, more flexible and efficient, and the only one in this comparison to publish the shape of the area an IP address relates to rather than a single point.

Technical comparison
The table below compares 51Degrees to other leading IP intelligence providers across the measures that matter when choosing a solution. The measures where the providers differ most come first. 51Degrees is the only provider in the table to return the shape of the area as a Well Known Text polygon, to weight alternative results by how likely each one is, and to randomize coordinates so the output protects privacy. Each competitor fact links to the source it was taken from. Where a provider does not publish a fact, the cell says Unpublished rather than guessing.

51Degrees builds its IP intelligence from the registration records published by the five Regional Internet Registries (AFRINIC, APNIC, ARIN, LACNIC, and RIPE NCC), the bodies that allocate every IP address in use. Registration records state who each block of addresses is allocated to. Some other approaches lean on routing registries, which are separate databases describing how traffic may be routed, and which have documented staleness and forgery problems. See RFC 7682, the RIPE Labs study The IRR Landscape: Data Quality, and the CAIDA paper IRRegularities in the Internet Routing Registry for the evidence.

Source: Digital Element FAQ, which states more than 20 data sources and signals, weekly updates for NetAcuity geolocation data, granularity to sub-postal levels, and deployment through API access, cloud delivery, and file-based formats. The FAQ does not name file formats, a confidence or radius field, a free version, prices, or ISO accreditations.
See the IP Intelligence documentation for the properties returned and the on-premise and cloud deployment options, and the Area feature documentation, which describes the area polygons, the most likely coordinates within them, and the minimum and maximum accuracy radius properties. The area is returned as a Well Known Text vector geometry object. Well Known Text is an open standard for describing shapes, so the returned area can be drawn on a map or used directly in common mapping and database tools. As the IP intelligence page explains, returned coordinates are a randomized location to within circa 1 km of the user's actual position, refreshed once a day, so the result protects privacy while remaining useful.
Source: MaxMind GeoIP Databases page, which lists granularity from continent to approximate coordinates, the accuracy radius in kilometres that MaxMind says must accompany its coordinates, MMDB and CSV formats, weekday updates for the majority of databases, database and web service delivery, and public prices.
Source: IPinfo IP to Geolocation Database (Extended), which lists the fields returned, including a radius field described as the accuracy radius in kilometres.
Source: MaxMind IP Geolocation Data support article, which defines the mappable area MaxMind returns as a circle with its centre at the returned latitude and longitude and an accuracy radius. No polygon or other vector geometry output is described.
See the IP Intelligence overview, which describes country, region, and city results carried with a probability weighting. Where the evidence supports more than one answer, each value is returned with a weighting showing how likely it is, so an application can act on the certainty of the result rather than a single guess.
Source: MaxMind web services response documentation, which describes a single returned location per lookup, with values from 0 to 100 representing MaxMind's confidence that the returned country, city, or postal code is correct. These values are returned by the GeoIP web services and are not part of the downloadable databases.
A location confidence indicator and a coordinate accuracy radius answer different questions, so the table shows them as separate rows. A confidence indicator says how far to trust the returned place, for example whether the town should be relied on at all. An accuracy radius is a distance in kilometres around the returned coordinates within which the user is expected to be. A provider can offer one without the other, and the mechanisms are not interchangeable.
See the 51Degrees LocationConfidence property, which returns High, Medium, Low, or Unknown. High results can be relied upon for all practical purposes, Medium results are useful where the use case can tolerate a degree of inaccuracy, and Low or Unknown results should be discarded where the outcome matters. Read the location confidence blog post for the measurements behind the bands.
Data files can be kept current automatically through every 51Degrees SDK. See the automatic data file updates documentation.

See the SDK source on GitHub for 51Degrees (European Union Public Licence 1.2), MaxMind (Apache 2.0), and IPinfo (Apache 2.0). The licence covers the SDK code. The data the SDKs read is licensed separately by each provider.
Free versions differ widely in what they contain. The 51Degrees Lite data file carries the registered name, owner, and country of each network and no town or coordinate data (see the IP Intelligence documentation). MaxMind describes free GeoLite2 city data as considerably less accurate than the paid GeoIP data. IPinfo Lite carries country-level location and network details only. Free versions also update less often than the paid versions.

51Degrees holds ISO 9001 and 27001 standards for quality and information security management. Read more about how and why we embraced ISO.
Source: MaxMind Commitment to Security, which states an information security management system based on the ISO 27001 standard and a completed SOC 2 Type II audit. MaxMind does not claim ISO certification itself, so the cell records the audit and the standard it is based on rather than an accreditation.
Other providers exist beyond those shown, which match the accuracy comparison above. DB-IP offers commercial databases with daily updates in CSV and MMDB formats and a free Lite edition updated monthly, and IP2Location offers downloadable databases in several formats with a free LITE edition.
