Saya tahu IPv6 memungkinkan nol berturut-turut dihilangkan. Tapi bagaimana dengan IPv4? Saya belum menemukan referensi untuk ini di Internet, termasuk Wikipedia dan RFC 791 - Protokol Internet. Dokumen ini menyarankan bahwa "Leading nol dapat dihilangkan" di alamat IPv4 (cari istilah 'dihilangkan'). Tidak cukup spesifik.
Lihatlah sesi shell ini:
[~]$ ping -c 1 127.1

Jelas, baik ping dan ssh mengerti 127.1 dan 127.0.1 sama dengan 127.0.0.1. Di mana ini ditentukan?
ping 0.0.0.0
atau ping 0
bekerja dengan cara yang sama ...)
