In the IP protocol, there are several standards that ought to be followed regarding particular interpretations of IP-addresses.
The following special IP addresses are defined by international standards:
- If the overall IP-address involves only binary zeros, then it indicates the address of the node that generated the packet. This mode is barely utilized in some reports of ICMP protocol.Â
- If the network number within the field are just zeros, then the default is that the destination node belongs to an identical network because the node that sent the packet.Â
If all of the bits of the IP-address are equal to at least one, the packet with this destination address must be sent to all nodes at the same network because the source of this packet. This traffic flow known as a limited or directed broadcast. - If the number field of the destination node are just ones, the packet has an address that's sent to all network nodes with a given network number. For instance, consider the network 192.190.21.0 with mask 255.255.255.0. Then a packet with destination address 192.190.21.255 is a packet which need to be dropped at all network nodes of the particular network. This communication known as a printed message.
IP addressing and IP configuration are concepts which are core in computer networking, so while you're interested to pursue a networking certification (along with Cisco CCNA for instance) you ought to learn all information about IP addresses and routing.
