0.0.0.0/0 Special CIDR Block Math


0.0.0.0 is the Network Address in 0.0.0.0/0
CIDR block	0.0.0.0/0 !cidr !bgp
Valid CIDR block	0.0.0.0/0
Range: Network - Broadcast	0.0.0.0 - 255.255.255.255
Netmask	0.0.0.0
Number of IP addresses in the block	4294967296 (4.294967e+09)
Network Address: 0.0.0.0 !ip !rdap !whois !bl !ptr24 !scan !tr !dnstr !g !gsec
Broadcast Address: 255.255.255.255 !ip !rdap !whois !bl !ptr24 !scan !tr !dnstr !g !gsec
0.0.0.0/32 - "This host on this network." 0.0.0.0/32 was allocated on September of 1981. 0.0.0.0/32 may be used as the source address of an IP datagram that transits two devices. 0.0.0.0/32 may NOT be used as the destination address of an IP datagram that transits two devices. 0.0.0.0/32 is NOT forwardable. A router may NOT forward an IP datagram to 0.0.0.0/32 between external interfaces 0.0.0.0/32 is NOT globally reachable An IP datagram may NOT be forwarded to 0.0.0.0/32 beyond a specified administative domain. The RFC that created 0.0.0.0/32 requires all compliant IP implementations to behave in a special way when processing packets either to or from addresses contained by 0.0.0.0/32 0.0.0.0 MUST NOT be sent, except as a source address as part of an initialization procedure by which the host learns its own IP address.
