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.
