Is it possible to switch from IPv4 to IPv6?
IPv6 is not backward compatible with IPv4, and IPv4 hosts and routers will not be able to deal directly with IPv6 traffic and vice-versa. In fact that there will be extreme difficulties with address allocation and routing if the internet is to continue to run indefinitely using IPv4.
Do you need both IPv6 and IPv4 on your intranet?
- Ready or not, you're going to need to use both IPv6 and IPv4 on your corporate intranet and to connect to the Internet for years to come. Here are some ways to do it. It would have been so easy if the early Internet and TCP/IP network designers had made IPv6 backward compatible with IPv4. They didn't.
What is IPv6 and why does it matter?
- The Internet’s ability to function is predicated upon each device having a unique Internet Protocol (IP) address and thus, a new address schema called IP version 6, or IPv6, was implemented so that the ever-growing number of “things” on the Internet can function properly.
How can IPv4 and IPv6 co-exist together?
- IPv4/IPv6 co-existence can take one of three forms.. One is dual stack, where your network hardware runs IPv4 and IPv6 simultaneously. Next is when you " tunnel " one protocol within another. Usually, this means taking IPv6 packets and encapsulating them in IPv4 packets.
What is IPv4/IPv6 compatibility and how does it work?What is IPv4/IPv6 compatibility and how does it work?
To support IPv4/IPv6 compatibility, a scheme was developed to allow IPv4 addresses to be embedded within the IPv6 address structure. This method takes regular IPv4 addresses and puts them in a special IPv6 format so they are recognized as being IPv4 addresses by certain IPv6 devices.
What is IPv6/IPv4 address embedding?What is IPv6/IPv4 address embedding?
IPv6/IPv4 Address Embedding. IPv6 is backward compatible with IPv4, provided that special techniques are used. For example, to enable communication between "islands" of IPv6 devices connected by IPv4 networks, tunneling may be employed. To support IPv4/IPv6 compatibility, a scheme was developed to allow IPv4 addresses to be embedded within...
What is the transition from IPv4 to IPv6?What is the transition from IPv4 to IPv6?
This means that there will be a progressive transition (picking up pace from this point forward) from IPv4 to IPv6 commencing with devices that support both protocols (also known as dual stacking). Eventually, IPv4 will cease to be supported and in the end, all IPv4 only devices will no longer be able to communicate with the IPv6 enabled Internet.
What is IPv6 tunneling and how does it work?What is IPv6 tunneling and how does it work?
In tunneling, one protocol is carrying inside another. Usually, that's going to be IPv6 in IPv4. These tunnels can move your IPv6 packets across both your internal IPv4 WAN and the mainly IPv4 Internet, Someday, when IPv6 becomes the top Internet protocol, we'll use IPv6 tunnels to carry IPv4 traffic.
