The LOC record (RFC1876) is a means for expressing location information in the Domain Name System. It contains WGS84Latitude, Longitude and Altitude information together with host/subnet physical size and location accuracy. This information can be queried by other computers connected to the internet. The Domain Name System or DNS is a system that stores information about hostnames and domain names in a type of distributed database on networks, such as the Internet. ... WGS 84 is the 1984 revision of the World Geodetic System. ... Latitude, denoted by the Greek letter φ, gives the location of a place on Earth north or south of the Equator. ... Map of Earth showing curved lines of longitude Longitude, sometimes denoted by the Greek letter λ, describes the location of a place on Earth east or west of a north-south line called the Prime Meridian. ... Altitude is the elevation of an object from a known level or datum, called zero level. ... The word subnet may refer to: An abbreviation for subnetwork A mathematical net. ...
The altitude range provides the following: A geosynchronous orbit is a geocentric orbit that has the same orbital period as the sidereal rotation period of the Earth. ... Earth, also known as the Earth, Terra, and (mostly in the 19th century) Tellus, is the third-closest planet to the Sun. ... For other uses, please see Satellite (disambiguation) A satellite is an object that orbits another object (known as its primary). ...
DNS altitude range [-100000.00 .. 42849672.95]. This range can be easily stored in 4 bytes.
Maximum altitude is 42,849.67295 km. Which is large enough to store the altitude of a circular geosynchronous orbit (i.e. approximately 35,790 km above mean sea level).
Maximum depth of 100 km below earth surface.
The Domain Name System or DNS is a system that stores information about host names and domain names in a kind of distributed database on networks, such as the Internet. ...
If there is no LOCrecord for that name, all A records associated with the name MAY be checked for network (or subnet) LOCrecords using the "searching by network or subnet" algorithm.
Reverse the octets, suffix IN-ADDR.ARPA, and query for PTR and A records.
Other values indicate that the entire record should be ignored to allow for future implementations of the RR to be later created.
This is because those records are handled by the zone parent DNS servers (for example, the.com DNS servers if your domain is example.com), which typically cache those records for 48 hours.
For example, this record is used to implement the Sender Policy Framework specification.
Other types of records simply provide information (for example, a LOCrecord gives the physical location of a host), or experimental data (for example, a WKS record gives a list of servers offering some well known service such as HTTP or POP3 for a domain).
