FAQ

Was is CIDR notation?
CIDR (Klasseless Inter-Domäne Routing) notation combines an IP address with a prefix length, like 192.168.1.0/24. The /24 means the first 24 bits are the network portion, equivalent to subnet mask 255.255.255.0.
Was is the broadcast address?
The broadcast address is the last address in a subnet, used to send data to all hosts on that network. Zum Beispiel, in 192.168.1.0/24, the broadcast is 192.168.1.255.
Wie many usable hosts are in a /24 subnet?
A /24 subnet has 256 total addresses. Nachher reserving the network address (.0) and broadcast address (.255), there are 254 usable host addresses.
Is this calculator free?
Yes, completely free. Alle Berechnungen happen in Ihrem Durchsuchenr with kein Server calls.
