What is ENUM?
We inform about NASK's withdrawal of services related to the use of numbers in the domain 8.4.e164.arpa (the so-called ENUM). The planned withdrawal of services will take place on 31 August 2019. After this date, there will be no technical possibilities for NASK Partners to provide services in the scope of using numbers in domain 8.4.e164.arpa.
ENUM is a technology platform enabling the transformation of phone numbers from E.164 standard into domain names in the Domain Name system (DNS). DNS enables translating domain names into IP addresses. Obtaining an IP address (e.g. of a server where a www server, servicing a domain name is held) for ENUM is not essential, in general it is about binding different telecommunication services with a phone number recorded as a domain name. ENUM uses NAPTR RR (The Naming Authority Pointer DNS Resource Record) in order to specify what services are bound with a particular domain name. Each NAPTR contains URI (Uniform Resource Identifier) description specifying the method of contact with the owner of a number. Therefore, a registrant may apply one universal number (identifier) while using a variety of telematics services.
Currently, only one Partner assists in registration of ENUM domains:
