Placeholder: 1.0.0.0/16

• Status: Placeholder — detailed investigation pending
• Coverage role: Fills the address-space gap after 0.0.0.0/8
• Range: 1.0.0.0/16
• First address: 1.0.0.0
• Last address: 1.0.255.255
• Top-level registry: APNIC
• Top-level allocation evidence: IANA designates 1.0.0.0/8 (001/8) to APNIC
• Checked: 2026-07-22

What is known

IANA's IPv4 Address Space registry marks the encompassing 1.0.0.0/8 block as allocated to APNIC. This file exists to provide explicit, contiguous repository coverage between 0.0.0.0/8 and the narrower researched 1.1.1.0/24 range.

What is not yet known

This /16 is a repository coverage aggregate, not a claim that the whole range has one registrant, route origin, operator, or service. It may contain many smaller allocations and BGP announcements.

Research must still determine and split out:

• authoritative APNIC RDAP prefixes and resource holders;
• current covering and more-specific BGP announcements;
• origin ASNs and RPKI status;
• documented operators and services;
• special cases and notable exact addresses.

Until that work is complete, no single “owner” should be inferred from this placeholder.
