Am tot auzit despre „greșeala” celor de la RDS și anume alocarea de adrese IP ce se termină în .0 (punct zero).

Addresses ending in 0 or 255
Main article: IPv4 subnetting reference
It is a common misunderstanding that addresses ending with an octet of 0 or 255 can never be assigned to hosts. (See also Subnet – all zeros or all ones.) This is only true of networks with subnet masks of at least 24 bits — Class C networks in the old classful addressing scheme, or in CIDR, networks with masks of /24 to /32 (or 255.255.255.0–255.255.255.255).
In classful addressing (now obsolete with the advent of CIDR), there are only three possible subnet masks: Class A, 255.0.0.0 or /8; Class B, 255.255.0.0 or /16; and Class C, 255.255.255.0 or /24. For example, in the subnet 192.168.5.0/255.255.255.0 (or 192.168.5.0/24) the identifier 192.168.5.0 refers to the entire subnet, so it cannot also refer to an individual device in that subnet.
