DNS cache

RouterOS General
1

It seems like the mikrotik is keeping the DNS entries in cache a lot longer than their TTL?

TTLs with 5 minutes are in the cache table for 1 hour. Is there a reason for this?

Are you sure the reply coming of one TTL of 5 minutes?

you know what… I’m using unotelly DNS, and it seems they make everything one hour minimum… really! Thats a pain in the butt!

RouterOS version?

I have 6.15 on both DNS Servers and my local router, but the entry are dynamic (3min [clients.l.google.com], 5 min [any.edge.bing.com], 30 sec, etc.), not forced to 1h

For security I flush DNS for see if really 5 min DNS are fresh on not timeouted from 1h…

Thanks for the help, but the last post I made is saying its not the mikrotik, its the unotelly DNS service that is changing it from 5 minutes to 1 hour. (And there is nothing wrong with the RouterOS).

Thanks again.
