I'm not sure this is such a good idea. A) there are may kinds of tunnels, like IPv6/UDP/IPv4 or GRE, or L2TP or... Not sure limiting to Ipvx/Ipvy is that useful B)A node can literally terminate gazillions of tunnels... Think about a Mobile Agent or a softwire concentrator... So ICMP name lookup would end up revealing information that may not be adequate to reveal, but more, this could be turned into a fabulous amplifier for DOS attack if ever the Home Agent, realizing that all the addresses do not fit in a single packet, decide to respond So, my recommendation is to not include this feature. - Alain. -------------------------------------------------------------------- IETF IPv6 working group mailing list ipv6@ietf.org Administrative Requests: https://www1.ietf.org/mailman/listinfo/ipv6 --------------------------------------------------------------------
