Seems that the default Max Packet Size is 512 on the DNS cache. I also hear that due to DNSSEC 512 is not big enough. In past have just handed out the Mikrotik router as DNS server and set the parent to our upstream.
Does Max Packet Size need to be bigger? Due to DNSSEC do we just want to not use the built in cache anymore? Anyone having issues with the built in DNS cache?
