Exposing these attributes makes it easier to write display code that can handle both IPv4 and IPv6 addresses. packed¶ The binary representation of this address - a bytes object of the appropriate length (most significant octet first). This is 4 bytes for IPv4 and 16 bytes for IPv6. reverse_pointer¶ IPv6 - Wikipedia Câmpul de lungime din IPv6, fata de IPv4 (8 biti=1 byte=1 octet), are 16 biți, ceea ce însemna că dimensiunea pachetului este de maxim 2 16 - 1 = 65.535 octeți de date. Totuși, standardul IPv6 prevede existența unui antet opțional numit Jumbo Payload, care permite folosirea a maxim 2 32 - 1 = 4.294.967.295 octeți de date pe conexiunile IPv4 ToS/IPv6 traffic class byte In an IPv6 packet, the Traffic Class byte is used in the same way as the ToS byte in an IPv4 packet. A ToS/Traffic Class byte includes a DSCP codepoint and precedence bits: Differentiated Services Codepoint (DSCP) Consists of the upper six bits of the ToS/Traffic Class byte. There are 64 possible codepoints. Intro to Networking Chapter 5 Quiz Flashcards | Quizlet

" SYNTAX OCTET STRING (SIZE (0..16)) Ipv6AddressIfIdentifier::= TEXTUAL-CONVENTION DISPLAY-HINT " 2x:" STATUS current DESCRIPTION " This data type is used to model IPv6 address interface identifiers. This is a binary string of up to 8 octets in network byte-order. IPv6 Summarization Example - NetworkLessons.com Summarizing IPv6 prefixes is similar to IPv4 summarization, the big difference is that IPv6 uses 128 bit addresses compared to 32 bits for IPv4 and IPv6 uses hexadecimal addresses. In this lesson, I’ll explain how to create IPv6 summaries and we’ll walk through some examples together.

IPv4 uses 32 bits so it has 4 octets. IPv6 uses 128 bits, so it has 16 octets. However we express IPv6 addresses as 8 16 bit numbers(hexadecimal notation).
