Re: ipv4 and ipv6 Coexistence.

[David Farmer <farmer@xxxxxxx>]

Ignoring the discussion about IPv6 adoption (or lack thereof) and answering the question about coexistence;

NAT64 frequently coupled with DNS64 is the primary mechanism for coexistence between IPv4 and IPv6, see the following as a starting point;

RFC6144 - Framework for IPv4/IPv6 Translation 

RFC6146 - Stateful NAT64: Network Address and Protocol Translation from IPv6 Clients to IPv4 Servers

RFC7755 - SIIT-DC: Stateless IP/ICMP Translation for IPv6 Data Center Environments - for IPv4 Client to IPv6 Servers

Hope this helps.

Hi,

 

Just a quick question as it is long time since I didn’t keep track of the new IETF work, but from what I see in the real world, I would like to make this question here.

 

Is there any “new” solution that became a standard or in the standard track for the IPv4 depletion problem that will allow IPv4 and IPv6 to coexist and communicate to each other’s in a peaceful way without any complications?

 

From what I see in the real world, IPv4 still dominating and almost nobody started using IPv6, and also, I didn’t find any solution applied practically in today’s networks for this issue..

 

All what I can see is begging people to move to IPv6...

 

Best Regards,
