Hi Tal,

Attraktive feature, offering a better defined alternative to playing TTL games to get some parts of the received forward IP headers back.

quick question, what about IPv4? Given that IPv4 will be with us for the foreseeable future it would be IMHO a good idea trying to keep ICMPv4 and ICMPv6 better aligned. Are there any obvious reasons (factual or procedural) I might be missing why restricting this to ICMPv6 is the best path forward?

Regards
	Sebastian
