Why IPv6 ?

[mani5raja]

Hello,

What does this sentence below mean ?

"IPv4 enabled clients can be configured manually or they need some address configuration mechanism. It does not have a mechanism to configure a device to have globally unique IP address."

I found the sentence in the below link.

"IPv4 enabled clients can be configured manually or they need some address configuration mechanism. It does not have a mechanism to configure a device to have globally unique IP address."

Configured manually -> a human being must type in the IP-address in a software control panel.
Address configuration mechanism -> a computer can ask another computer via the network to give it an IP address. E.g. DHCP works this way.

With IPv6 there is a 3rd way to determine your own IP-address.
Called SLAAC. A router tells the computer the network-part of the address. The computer must come up itself with a unique number for the host-part. E.g. it can use its MAC-address. Combining the given network-part and the chosen host-part, create an IPv6 address.

Daily experience has convinced most network managers that SLAAC is not worth the trouble. And DHCPv6 is the better option.

Remember kids: IPv6 is exactly like IPv4, same drawbacks, and no more benefits. And a lot of added unnecessary complexity.
