What is IPv6 simple?
An IPv6 address is a 128-bit alphanumeric value that identifies an endpoint device in an Internet Protocol Version 6 (IPv6) network. IPv6 is the successor to a previous addressing infrastructure, IPv4, which had limitations IPv6 was designed to overcome.
What are IPv6 basic capabilities?
Expanded routing and addressing capabilities – IPv6 increases the IP address size from 32 bits to 128 bits to support more levels of addressing hierarchy. In addition, IPv6 provides a greater number of addressable nodes. IPv6 also employs simpler autoconfiguration of addresses.
What is IPv6 example?
An IPv6 address is represented as eight groups of four hexadecimal digits, each group representing 16 bits The groups are separated by colons (:). An example of an IPv6 address is: 2001:0db8:85a3:0000:0000:8a2e:0370:7334.
What is the purpose of IPv6?
IPv6 (Internet Protocol version 6) is the sixth revision to the Internet Protocol and the successor to IPv4. It functions similarly to IPv4 in that it provides the unique IP addresses necessary for Internet-enabled devices to communicate.
What are three important features of IPv6?
IPv6 – Features
- Larger Address Space. In contrast to IPv4, IPv6 uses 4 times more bits to address a device on the Internet.
- Simplified Header.
- End-to-end Connectivity.
- Auto-configuration.
- Faster Forwarding/Routing.
- IPSec.
- No Broadcast.
- Anycast Support.
What is the protocol used in IPv6?
IPv6 implements the Neighbor Discovery Protocol (NDP, ND) in the link layer, which relies on ICMPv6 and multicast transmission.
What are the advantages of IPv6?
Key benefits to IPv6 include:
- No more NAT (Network Address Translation)
- Auto-configuration.
- No more private address collisions.
- Better multicast routing.
- Simpler header format.
- Simplified, more efficient routing.
- True quality of service (QoS), also called “flow labeling”
- Built-in authentication and privacy support.
What protocols does IPv6 use?
IPv6 is an Internet Layer protocol for packet-switched internetworking and provides end-to-end datagram transmission across multiple IP networks, closely adhering to the design principles developed in the previous version of the protocol, Internet Protocol Version 4 (IPv4).
How do I remember IPv6 addresses?
1) Remembering an IPv6 address isn’t that hard if you really want to remember it and you do things sanely. And it’s only 32 digits not that horrible. The first 64-bits (16 digits) of the IPv6 address is going to come from your ISP, so should almost always be the same.
How many host we can connect in IPv6?
340,282,366,920,938,463,463,374,607,431,768,211,456 addresses
The size of an IPv6 address is 128 bits, compared to 32 bits in IPv4. The address space therefore has 2128 = 340,282,366,920,938,463,463,374,607,431,768,211,456 addresses (approximately 3.4×1038).
