4 Electronic or E.164 NUMber mapping is defined by the Internet Engineering Task Force (IETF) in RFC3761 as: the mapping of „Telephone Numbers“ to Uniform Resource Identifiers (URIs) using the Domain Name System (DNS) in the domain e164.arpa URIs are used to identify resources on the Internet (e.g. http://enum.nic.at ) http://enum.nic.at The purpose of ENUM is to enable the convergence between the PSTN and the Internet ENUM is defined by the IETF

14 How to Install ENUM Server? Instal DNS Server. Pada linux, biasanya sudah ada paket BIND yang merupakan DNS server yang dapat dioperasikan dengan mudah. Edit file /etc/named.conf untuk memberitahu sistem tentang letak data untuk domain yang kita buat. Edit file data ENUM untuk memasukkannomor telepon tiap pelanggan.

15 How to Install ENUM Server? Misal kita memperoleh alokasi nomor +6255566666600 s.d +6255566666699. Maka kita perlu mengedit file /etc/named.conf untuk domain 6.6.6.6.6.6.5.5.5.2.6.e164.id dengan cara menambahkan entri : Zone ”6.6.6.6.6.6.5.5.5.2.6.e164.id” IN { type master; file ”6.6.6.6.6.6.5.5.5.2.6.e164.id.db”; allow-update { none; }; };

16 Semua data nomor telepon harus dimasukan ke file 6.6.6.6.6.6.5.5.5.2.6.e164.id.db yang pada Fedora Core 5 terletak di /var/named/chroot/var/named/6.6.6.6.6.6.5.5.5.2.6.e164.id.db. contoh isi file 6.6.6.6.6.6.5.5.5.2.6.e164.id.db adalah sebagai berikut : $TTL 86400 @IN SOA ns.warnet.co.id admin warnet.warnet.co.id.
