Abstract

This memo defines a new DNS RR type for experimental purposes. This RFC describes a mechanism to allow the DNS to carry location information about hosts, networks, and subnets. Such information for a small subset of hosts is currently contained in the flat-file UUCP maps. However, just as the DNS replaced the use of HOSTS.TXT to carry host and network address information, it is possible to replace the UUCP maps as carriers of location information.

This text was extracted from a ASCII document.
This is the abbreviated version, containing approximately 10% of the total text.

1. Abstract

This memo defines a new DNS RR type for experimental purposes. This

RFC describes a mechanism to allow the DNS to carry location

information about hosts, networks, and subnets. Such information for

a small subset of hosts is currently contained in the flat-file UUCP

maps. However, just as the DNS replaced the use of HOSTS.TXT to

carry host and network address information, it is possible to replace

the UUCP maps as carriers of location information.

This RFC defines the format of a new Resource Record (RR) for the

Domain Name System (DNS), and reserves a corresponding DNS type

mnemonic (LOC) and numerical code (29).

This RFC assumes that the reader is familiar with the DNS [RFC 1034,

RFC 1035]. The data shown in our examples is for pedagogical use and

does not necessarily reflect the real Internet.
