"This network" · RFC 1122

The "current network" — used as a source address during bootstrapping when a host does not yet know its own IP. Not valid as a destination on the public internet.

This range is reserved by IANA — it is not allocated to an organization, ISP, or regional internet registry. Addresses here appear on every private/internal network that follows the standard, so lookups will not identify a specific owner.

Frequently Asked Questions

What is 0.0.0.0/8?

0.0.0.0/8 falls inside 0.0.0.0/8 — a "This network" range reserved by RFC 1122. The "current network" — used as a source address during bootstrapping when a host does not yet know its own IP. Not valid as a destination on the public internet.

Is 0.0.0.0/8 routable on the public internet?

No. 0.0.0.0/8 is part of IANA-reserved special-use space (0.0.0.0/8, RFC 1122). Packets with these addresses are either filtered by backbone routers or handled as local/special traffic — they never reach the public internet.

Who owns 0.0.0.0/8?

0.0.0.0/8 is not allocated to any organization or ISP. It is part of the "This network" block reserved by IANA under RFC 1122 for every network to use privately.
