Jamie,
Thank you. I did read several forum posts about this "router delay"
perception. I do not think I got a complete picture of medium/high
level "intranet" behavior. Most of the forum noise was about a pair of
routers that did NOT seem to do "DNS Relay." Either at all, or,
properly. Yes, I accept that any/all 'time' related business, to me,
falls into my bench-racing bit-bucket.
Another router option to play with, perhaps.
[1]My router has a "DNS Relay" option/switch. (disabled).
[2]It also allows me to tell it (enter) both a Primary and Secondary DNS
address (my choices).
I use [2] at the moment.
I was asking about the use/abuse of "DNS Relay" at my router, and, what
might happen if/when I enable it. I can very easily (30min.) for all my
clients. Yes, I know that my router (to me!) is a black box on my LAN. I
think (?) I know its' basics. Nothing more........... :)
I remain very happy that it continues to do whatever magic it contains!
Thanks,
Duncan

Clients will query the router, and the router will query your configured
DNS servers if it needs to. Unless configured otherwise, clients won't
go directly to your ISP's DNS servers.
The advantage of this is that if the router already has the answer then
it can just give it - it caches results for all clients that use it. The
disadvantage is that the router may actually slow down DNS queries by a
tiny amount - it's more work to process the queries and check its
internal cache (if the entry is not cached) instead of letting the
client go directly to your ISP's server. The difference is so small that
I doubt there's any way you would ever notice. It also lets you easily
switch DNS servers for all your clients if they use the router - only
one place to change instead of visiting each client.
It's most useful when clients get their configuration through DHCP.
It seems that I push more work upstairs where services exist, rather
than churning around within my LAN where answers do not exist. And
no, I do NOT use a Domain Server, yet!
Thank you,
Duncan
This has nothing to do with Windows domains - DNS has existed and been
working for longer then Windows has been on networks.
