The IP address 0.0.0.0 has several special meanings on computer networks.

However, it can not be used as a general-purpose unit address.

This IP address is structured like a regular one (it has four places for numbers).

It’s easy to confuse 0.0.0.0 and127.0.0.1.

The 0.0.0.0 IP address is sometimes called a wildcard address, unspecified address, or INADDR_ANY.

A rig might give itself this address by default whenever it is offline.

It might also be automatically assigned byDHCPin the case of address assignment failures.

When set with this address, a rig cannot communicate with any other devices on that data pipe.

0.0.0.0 can also theoretically be set as a gadget’ssubnetmask rather than its IP address.

However, a subnet mask with this value has no practical purpose.

Both the IP address and connection mask are typically assigned 0.0.0.0 on a client.
