# 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.
