We all know that the first address of any sub-net is network identifier and it can't be assigned to any hosts. For example in network 10.1.1.4/30, the address 10.1.1.4 is network identifier.
If suppose I ping this address from one of the hosts in the sub-net, who are all will reply me?
- Is there any specification in RFCs on this behavior?
- Could you please show me the code reference in Linux kernel handling ICMP_REQUEST with all-zero host-bit address.
Thanks in advance.
