## Authoritative IANA IPv4 datasets
- `iana-ipv4-top-level-ranges.csv` normalizes all 256 records from the IANA IPv4 Address Space Registry. Together they cover the complete IPv4 address space at `/8` granularity.
- `iana-ipv4-special-ranges.csv` normalizes and expands all IANA IPv4 Special-Purpose Address Registry entries, including source/destination, forwarding, global-reachability, and protocol-reservation properties.
Both datasets include source URL, verification date, and the corresponding Markdown filename. They are generated by [`scripts/sync_iana_ipv4.py`](../scripts/sync_iana_ipv4.py); do not treat top-level registry authority as exact-address ownership or current route operation.

# 0.0.0.0/32 — This host on this network
## Who is this IP range?
IANA identifies **0.0.0.0/32** as **This host on this network** special-purpose IPv4 space. This is a protocol or standards classification, not an assertion that one company owns or operates every address in the range.
## Special-purpose properties
- **Range:** `0.0.0.0/32`
- **Name:** This host on this network
- **RFC/reference:** [RFC1122], Section 3.2.1.3
- **Allocation date:** 1981-09
- **Termination date:** N/A
- **Valid as source:** True
- **Valid as destination:** False
- **Forwardable:** False
- **Globally reachable:** False
- **Reserved by protocol:** True
- **Checked:** 2026-07-22
## Interpretation
The properties above are copied from the authoritative IANA special-purpose registry. Footnote markers are retained because exceptions and qualifications matter. Routing or operational claims require separate current evidence.

# 1.0.0.0/8 — IANA top-level IPv4 registry
## Who is this IP range?
At the top-level `/8` registry layer, IANA designates **1.0.0.0/8** to **APNIC** and the RDAP authority maps to **apnic**. This does not identify one holder or operator for every address inside the block; detailed attribution requires more-specific RDAP and BGP research.
## Registry record
- **Range:** `1.0.0.0/8`
- **IANA designation:** APNIC
- **Registry suffix:** `apnic`
- **IANA status:** ALLOCATED
- **Allocation/record date:** 2010-01
- **WHOIS authority:** whois.apnic.net
- **RDAP authority:** https://rdap.apnic.net/
- **IANA note:** None
- **Checked:** 2026-07-22
## Scope and limitations
This record identifies the authoritative **top-level `/8` disposition**. It does not enumerate the many more-specific allocations, assignments, route origins, operators, services, or exact addresses inside the range.
A registry designation is not proof of legal ownership, current routing, physical location, or service operation. Use more-specific RDAP, BGP, RPKI, and operator sources before making those claims.

# 10.0.0.0/8 — Private-Use
## Who is this IP range?
IANA identifies **10.0.0.0/8** as **Private-Use** special-purpose IPv4 space. This is a protocol or standards classification, not an assertion that one company owns or operates every address in the range.
## Special-purpose properties
- **Range:** `10.0.0.0/8`
- **Name:** Private-Use
- **RFC/reference:** [RFC1918]
- **Allocation date:** 1996-02
- **Termination date:** N/A
- **Valid as source:** True
- **Valid as destination:** True
- **Forwardable:** True
- **Globally reachable:** False
- **Reserved by protocol:** False
- **Checked:** 2026-07-22
## Interpretation
The properties above are copied from the authoritative IANA special-purpose registry. Footnote markers are retained because exceptions and qualifications matter. Routing or operational claims require separate current evidence.

# 60.0.0.0/8 — IANA top-level IPv4 registry
## Who is this IP range?
At the top-level `/8` registry layer, IANA designates **60.0.0.0/8** to **APNIC** and the RDAP authority maps to **apnic**. This does not identify one holder or operator for every address inside the block; detailed attribution requires more-specific RDAP and BGP research.
## Registry record
- **Range:** `60.0.0.0/8`
- **IANA designation:** APNIC
- **Registry suffix:** `apnic`
- **IANA status:** ALLOCATED
- **Allocation/record date:** 2003-04
- **WHOIS authority:** whois.apnic.net
- **RDAP authority:** https://rdap.apnic.net/
- **IANA note:** None
- **Checked:** 2026-07-22
## Scope and limitations
This record identifies the authoritative **top-level `/8` disposition**. It does not enumerate the many more-specific allocations, assignments, route origins, operators, services, or exact addresses inside the range.
A registry designation is not proof of legal ownership, current routing, physical location, or service operation. Use more-specific RDAP, BGP, RPKI, and operator sources before making those claims.
