Hi Ted, I do not understand you. You did copy my comment that was related to the capability of GRAND to alleviate ND exhaustion attacks. It was separate comment from Tony Finch. I could repeat again: no, it would not help against this type of attack, even if it would be slightly modified. But DoS is not extremely big problem – it was not my concern. This concern has been mentioned by many other people in this thread, but not me. This problem is not good too, but I could tolerate it (at least I am ready to trade-off it for performance). Leakage of information is much bigger problem that I could not tolerate. May be you are asking me about GRAND in general, then no - I do not think that it is a good idea to expand functionality using the most valuable feature of ND (Unsolicited NA). Unsolicited NA is very easy to create a leakage of information. IMHO: it is unacceptable problem that should be fixed first. If Unsolicited NA would be changed as a result of such ND modification – then GRAND would be based on new version of ND.

No need for standardization. I think I explained why it was worth standardizing from my perspective. Perhaps you disagree with that perspective, but you haven’t said why. The way you say this makes it sound like you think there’s a downside to standardizing. Can you explain what that downside is?
