Re: [dhcwg] Network Time Protocol (NTP) Options for DHCPv6

[Bud Millwood <[e-mail]>]

How many DHCP options are normally configured to point to services outside of 
the operator's domain? How many public SIP servers are there, for example?

As a server writer I have a built-in aversion to changing the way we 
distribute location of services, but in this case it seems justified to use a 
DNS name simply because the de-facto standard, as far as I can tell, is to 
point clients outside the admin-controlled domain. So maybe the projected use 
of the service has a real bearing on this discussion.

I've read this thread a little quickly, but it seems that we could end up 
passing multiple NTP server IP addresses to DHCP clients. If so, then the 
packet space argument against DNS names starts to break down the more 
addreses you distribute. At some point it would be less space to send the DNS 
name than a list of n addresses.

And as for the argument that a DNS name requires a resolver on the client: how 
big of an issue is this, really? How many devices are really likely to want 
to sync their clocks over NTP but not have even a rudimentary resolver?
