# IANA range: 0.0.0.0/8
|
|
|
|
## Who is this IP range?
|
|
|
|
**Short answer:** IANA reserves this range for protocol-defined “this network” use. It is not assigned to a company, ISP, cloud provider, or ordinary network operator.
|
|
|
|
- **Registry:** IANA
|
|
- **Range:** `0.0.0.0/8`
|
|
- **IANA name:** This network
|
|
- **Classification:** Special-purpose IPv4 space
|
|
- **Organizational holder:** None; reserved by the IP protocol
|
|
- **Globally reachable:** No
|
|
- **Verified:** 2026-07-20

|
## Range knowledge
|
|
|
|
IANA reserves `0.0.0.0/8` as “This network.” It is not an ordinary public allocation to an ISP, cloud provider, company, or person. IANA marks the block as not usable as a destination, not forwardable, and not globally reachable.
|
|
|
|
No normal BGP origin or global network operator should be inferred for this block.

## Investigated addresses
|
|
|
|
### 0.0.0.0
|
|
|
|
The exact `0.0.0.0/32` entry means “This host on this network.” It is used as an unspecified source address in limited host-initialization contexts and must not be treated as a normal destination.
