Versionsgeschichte interaktiv durchsuchen

Aktuelle Version vom 2. Juni 2025, 14:46 Uhr

Keine Prüfsummen

Es werden keine Prüfsummen über die IP-Kopfdaten berechnet
im Gegensatz zu IPv4
Fehlerkorrektur auf Schichten 2 und 4

Extension Headers

Optionale, seltener benutzte Informationen werden in Erweiterungs-Kopfdaten (engl.: Extension Headers) eingebettet

zwischen dem IPv6-Kopfdatenbereich und der eigentlichen Nutzlast (engl. Payload)

Verwendung

Next-Header-Feld

Extension Headers enthalten ein Next-Header-Feld

Nummer des nächsten Extension Header
oder des Upper Layer Protocol

Standard Header

IPv6 Header Next Header: TCP (06)	TCP (06) Header and data

Routing Header
