[Pdns-users] Latency and cache size are correlated

[Eugene Pefti]

Well, I tried to elaborate on our setup with an authoritative and recursor
servers running on one machine. It is mostly because of the legacy. The
company is in a small webhosting business and whenever clients register
their domains through registrar's interface they add the names of our DNS
servers as authoritative for those domains. On the other hand the company
provides shared and collocation services and lots of client servers use same
DNS IPs for recursive queries. That could be changed to a small extent
running caching only DNS server on some of them but the majority of clients
are reluctant to do any changes and this is why we have this mixed setup.
Thanks anyways, Chat, for an open mind and coming back to my question.

Hey Eugene-

 

I know you have a few issues you're trying to tackle- but I'm going to try
to focus on this one: ..you currently have people making recursive lookups
through your authoritative nameserver? Just making sure I'm reading that
right. If so, I don't entirely understand your reasoning- if you could
explain it again (in possibly a different way), we might be able to help you
come up with a better solution to split authoritative vs recursive lookups
so you're not mixing.

 

Talk to you soon, sorry if I'm asking the same question twice- thanks!

 

Chet

Thanks, Alan!

Unfortunately I can't set them apart. Lots of our clients use dns IPs to
recursing and same IPs are added to domain name registrars registries. A
thought came to me after reading your answer, if in my pdns.conf I allow
recursion for my networks only does it mean that none of the questions asked
by recursive servers will be answered by my authoritative server?

If you have clients asking the authoritative server for recursive data, then
you're mixing them. The authoritative server should normally only be asked
questions directly by recursive servers for data it's authoritative for.
