Hello all,

I have been reading on the forum about configuring dnsmaqs. There appears to be number of discussions for example:

https://forum.dd-wrt.com/phpBB2/viewtopic.php?t=313498&start=0&sid=486d24b8a79af4660b9920cd239c57bf

If third part DNS servers are specified in basic setup, do I leave section the additional DNSMasq section balnk? (as i think it is working okay)

Does any one know what is the correct but straight forward method to achieve best performance?.

Place the 3 fastest DNS servers you know in static DNS 1,2,3

Disable 'Query DNS in strict-order'

Is a good starting point.

If you disable DNSMasq it is not working anymore.

okay,In addition to
Disable 'Query DNS in strict-order'
I have inserted TWO ip4 and TWO IP6 dns servers (Adguard) in the basic setup with ignoring ISP servers.

should I go beyond this such as inserting anything in the additional DNSMasq or this is actually the best performance>

I aso did DNS leak test- it appears that only ip4 dns is used and not ip6?

do you actually have any ipv6 from your ISP?

If not disable the lot, even in the ethernet adapters on pcs etc.

Have a nice weekend.

I have ip6 from the ISP.

I checked with nslookup and it is resolving both ip4 and ip6 DNS. Just wondering if any other settings for DNS needs to be in place apart from the above to derive the most benefit from dd-wrt system?

Would It be also good to enable smart DNS as well? Would that further improve query return times...

Only if you know how to configure SmartDNS. There is information in the forum on what users' have contributed as far as working configurations, if I am not mistaken.

Thanks. There are only 3 options in the latest build

SmartDNS Resolver
Enable Disable
Dualstack IP Selection
Enable Disable
Prefetch Domain
Enable Disable
Serve Expired
Enable Disable

I read the https://forum.dd-wrt.com/phpBB2/viewtopic.php?t=323866&sid=1e6a01132f32ee435346b3d652306dd6

https://github.com/pymumu/smartdns/blob/master/ReadMe_en.md

Are there any other helpful pointers to keep in mind while expereminting with this

Not sure if anyone has an experience of using it and can share the outcomes ?
