IPv4/Adressraum
Beschreibung
- Allgemein gilt
- Anzahl der IPv4-Adressen = 232 - Länge der Netzadresse
- Erste und letzte IPv4-Adresse ist reserviert für Netzwerk- bzw. Broadcast-Adresse
- Adressbereiche der Größe /0 bis /7
- werden in der Praxis nicht als einzelnes Subnetz verwendet, sondern in mehrere Subnetze unterteilt
- /31-Netze enthalten keine nutzbaren Host-Adressen
- während /32 kein Subnetz, sondern immer einen einzelnen Host adressiert.
- Hierbei gibt es auch Ausnahmen. So wurde im RFC 3021 vorgeschlagen, dass /31-Netze genutzt werden, um Point-to-point-Verbindungen zu etablieren.
- Dies wurde unter anderem von der Firma Cisco implementiert.
- Des Weiteren ist es unter bestimmten Umständen möglich, die Netz- und Broadcastadresse für Hosts zu verwenden
