In 2000, the IAB informed the technical community that the .arpa has been re-designated as Address and Routing Parameter Area. The .arpa will serve as a single domain where all new infrastructure sub-domains will be placed to maintain the stability of the internet. The IAB also recommended to the Internet Engineering Steering Group ([[IESG]]) that no new infrastructure domains should be added to [[.int]] and protocols requiring specific domain roots should be rooted elsewhere, new infrastructure domains from the Internet Engineering Task Force ([[IETF]]) protocols must be allocated to the .arpa TLD. Management will be handled by IANA. In addition. the IAB also suggested the review of all existing IETF infrastructures allocated under .int if the costs of transferring them is greater than the risk of staying in place. The IAB believed that allocating the [[IPv6]] reverse mapping domain is more significant and beneficial. <ref>[http://www.iab.org/documents/correspondence-reports-documents/docs2000/iab-statement-on-infrastructure-domain-and-subdomains-may-2000/ IAB Statement on Infrastructure Domain and Subdomains, May 2000]</ref>

* E164.ARPA - mapping E.164 numbers to Internet URIs
* IN-ADDR-SERVERS.ARPA- hosting authoritative name servers for the in-addr.arpa domain
* IN-ADDR.ARPA- mapping [[IPv4]] addresses to Internet domain names
* IP6-SERVERS.ARPA- hosting authoritative name servers for the ip6.arpa domain
* IP6.ARPA- mapping IPv6 addresses to Internet domain names
* IRIS.ARPA- locating Internet Registry Information Services
* URI.ARPA- resolving Uniform Resource Identifiers ([[URI]]) according to the Dynamic Delegation Discovery System
* URN.ARPA- resolving Uniform Resource Names ([[URN]]) according to the Dynamic Delegation Discovery System
