recommending use of IN-ADDR.ARPA

    
    what does the DNS WG think about recommending usage of in-addr.arpa 
    for router networks in order to facilitate problem diagnostics?
Having IN-ADDR.ARPA nameservers should be considered mandatory
for all networks with Internet connectivity. Philip gave a very
good reason indeed for this:
	For users and network operators alike, this is a serious
	problem if we can't at least pin-point the locality of
	network outages.
This goes for network operators and systems managers, even when
the latter can/should contact their network operator(s): as a
systems manager I want to be able to quickly pinpoint the spot
of a network problem, so I can call on my experience as network
manager to be able to make a guess on how long it may last.

I must add though that I'm not at a complete loss when there is
no IN-ADDR.ARPA resolving for a particular router: I can check
the RIPE whois server to see whom the network belong too. Still
it's a nuisance if there is no IN-ADDR.ARPA resolving.
