IPv6 is the successor of IPv4. IPv4 and IPv6 are the Internet protocols to communicate to all networks. is IPv4 to dominate today over the Internet. The reason for IPv6 is simple, run the world out of IPv4 addresses. Sun IPv6 was created in 1998 to create more available public IP addresses. IPv4 provides about 4 billion addresses. To this into perspective the size of an IPv6-only subnet 2 in 64th Power. Or the square of the entire IPv4 Internet. To further setIn this perspective, with IPv6, you can 340 trillion trillion trillion unique addresses.
IPv6 uses 128-bit IPv4 addresses, which only uses 32 bit addresses. This increases the amount of available IP's. This eliminates the need for NAT or Network Address Translation. You can separate ports on your firewall Assing but use the same external IP. It will then route to various computer on the network.
IPv6 clients can configure themselves automatically if theyare connected to an IPv6 network using stateless address autoconfiguration. The way in which they will achieve this by ICMPv6 Router Discovery messages. If the first plugin to an IPv6 network, your host sends a link-local multicast router solicitation request. Which is basically a request for its configuration. Routers then send a router advertisement packet that contains the network layer settings. If you do not use Stateless Address Auto configuration There are two other options or DHCPv6You can configure your static address.
Security in IPv6 has also changed. Where IPsec is an option in IPv4 it was not in IPv6, it is mandatory.
In addition to other changes MIPv6 Mobile IPv6 or not triangular routing problems. Therefore, one could move in theory a whole subnet without numbering. to support your router but would NEMO network, or mobility. However, since NEMO and MIPv6 are widely distributed depolyed this is not common.
IPv6 addresses arewritten as follows 112: EC9: 97b4: 9b3f: 481:8445. IPv6 addresses are typically broken down into 2 parts logically. The 64-bit for the subnet and 64-bit for the host part of the address. Broadcast addresses no longer exist in IPv6, you now have three different types of addresses. You are Unicast, Anycast and Multicast. Unicast is a uniquely identifiable address for a host. Anycast is an address that is unique to a group of hosts usually in different physical locations are, so that dataflow one to the next. Multicast has not changed, it enables you to deliver a packet to multiple hosts.
As far as DNS goes, you can familiary with a host records. Or a name to an IPv4 address. With IPv6 you have an AAAA record, the IPv6 host its points.
Dual IP stack implementation is in most modern operating systems. It is a transitional path to run IPv4 and IPv6 simultaneously. In this way, programmers write applications to make connections across the IPv4 accept orIPv6 interfaces. Something else you will have the dual stack IPv6/IPv4 hybrid RUN addresses. These are special addresses where the first 80 bits are set to 0, the next 16 will be set to 1, and the last 32 bits are your IPv4 address. An example of a hybrid dual stack is as follows:: ffff: 192.168.1.1 you can see, it looks like an IPv4 address with the:: ffff: prefix.
Tunneling is a popular method of encapsulating IPv6 packets into IPv4 packets. What used IPv4 link layer for IPv6. Thisdirect encapsulation of IP Protocol 41 specified. If log is 41 on a router or a NAT device, you can also UDP packets to encapsulate your data block IPv6. Automatic Tunneling is a process in which the routing infrastructure determines the tunnel endpoints. 6to4 tunneling is recommended for automatic tunneling, using the protocol 41 encapsulation. Their endpoints are determined by the use of IPv4 anycast address on the remote side. Then integration of these local IPv6 address on the page. 6to4is now widespread and is probably the most common method of encapsulting. Configured tunneling is a different method of encapsulation. This is a process in which you explicitly configure your devices for your tunnel. This can be done by the operating system or manually by the administrator. There is also a method called automatic tunneling, where a tunnel broker. For larger networks, it is recommended because of its ease-configured routing problem in treatment compared to the automaticTunneling. Automatic Tunneling is a compromise between automatic tunneling and configured tunneling. It is the best of both worlds.
If you have a host, IPv6 is just keep in mind you must use a dual-stack application layer proxy, ie a web proxy. However, it must support both IPv4 and IPv6.
