6to4 (IPv6-to-IPv4)

Purpose of 6to4

6to4 is a technique for forwarding IPv6 packets over an IPv4 community without the want for an explicit tunnel configuration. It is ordinarily used to connect IPv6 networks separated with the aid of an IPv4 backbone along with the World Wide Web.

How 6to4 works?

The 6to4 router robotically encapsulates IPv6 packets into IPv4 packets and sends them over the IPv4 network. This ranking is based on a 6to4 prefix (commonly beginning with 2002::/16). The IPv6 packets are then decapsulated by means of some other 6to4 router on the receiving quit.

Advantage of 6to4 Mechanism

6to4 is extraordinarily smooth to use and does not require guide tunnels.

Disadvantage of 6to4 Mechanism

Relies on public IPv4 addresses, and NAT (Network Address Translation) can motive issues. 6to4 visitors may additionally encounter routing problems and suboptimal routes in a worldwide IPv4 community.

IPv4 transition mechanisms are designed to keep IPv4 and IPv6 networks constant during the transition from IPv4 to IPv6. These mechanisms help devices and networks communicate with each other, even when using different versions of IP. The three most common IPv6 switching protocols are 6to4, Teredo, and ISATAP.
