Monitoring IPv6-MAC mappings

[Phil Mayers]

All,

I had a couple of queries about my recent post asking how we did this, 
which surprised me; I thought it was a pretty tractable problem. We use 
a (very simple) bespoke system, but I was under the impression most 
people used one of the various open-source or commercial offerings (e.g 
NAV, Slaacer, and the like).

However - I then found I had trouble locating these in Google, perhaps 
because I wasn't picking the right terms, but maybe they don't have good 
Google Juice?

On that basis, what term(s) would people use to refer to systems that 
poll the network to record which MAC adress is using what IP (IPv6, IPv4 
optional!) and what products would people suggest / are people using? 
Bonus points for sensible handling of link-local addresses and subnets 
with >1 router.

[Bear in mind I don't need a product personally - we have in-house 
systems that do this - and things like RADIUS and DHCP logs are not 
quite what I mean]

Does anyone have suggestions for a good home that list could live, so it 
could get decent search engine rankings? It was suggested to me that 
some people consider lack of such monitoring a "blocker", so making 
these more find-able would be a plus.

Cheers,
Phil
