REGISTRI PROTOKOL

Registri parameter protokol mewakili catatan otoritatif dari banyak kode dan
nomor yang terkandung dalam berbagai protokol Internet. Kami menyimpan catatan
ini sesuai dengan standar teknis terkait dan kebijakan alokasi, dan kami
menyediakan layanan ini dalam koordinasi dengan Internet Engineering Task Force
(IETF).

Untuk melihat atau mengunduh pendaftar protokol individual, navigasikan ke
pendaftar individu melalui indeks di bawah ini. Data registri tersedia untuk
pengambilan massal melalui Rsync (disarankan) atau FTP .

Untuk mendapatkan pendaftaran di registri yang ada, atau untuk mengubah
pendaftaran yang ada, lihat formulir aplikasi yang relevan . Untuk informasi
tentang membuat registry baru, silakan lihat RFC 8126 untuk panduan.
