# Complete IANA IPv4 range index
|
||||
|
||||
Generated from authoritative IANA registries and checked **2026-07-22**.
|
||||
|
||||
## Coverage
|
||||
|
||||
- **256 top-level `/8` records**, covering all IPv4 addresses from `0.0.0.0` through `255.255.255.255` without gaps.
|
||||
- **26 expanded special-purpose prefixes** from the IANA IPv4 Special-Purpose Address Registry.
|
||||
- More-specific manual research records and placeholders remain alongside these authoritative baselines.
|
||||
|
||||
## Top-level counts
|
||||
|
||||
### By RDAP registry authority
|
||||
|
||||
- `afrinic`: 6
|
||||
- `apnic`: 51
|
||||
- `arin`: 111
|
||||
- `iana`: 35
|
||||
- `lacnic`: 10
|
||||
- `ripe-ncc`: 43
|
||||
|
||||
### By IANA status
|
||||
|
||||
- `allocated`: 129
|
||||
- `legacy`: 92
|
||||
- `reserved`: 35

## IANA special-purpose ranges
|
||||
|
||||
Special-purpose prefixes can overlap top-level `/8` records and each other because they express more-specific protocol semantics.

||||
