I tried this and it reports that 184.108.40.206 (dns3.ptd.net) is 132.6% faster than my current server 220.127.116.11 (dns.sth.ptd.net). Can someone please explain how I make the change to use the recommended configuration. Any details greatly appreciated.
Is it best to make the change in router setup - currently set to get DNS automatically from ISP. Should I change to "Use these DNS servers" and enter primary and secondary IP addresses there? How would you test to see results improvement? Speedtest.net shows download speed at advertised rate - is there another way to see speed differences from changing DNS? Will it find or resolve the address faster?
Edit: While waiting for advice I think I answered my own questions (probably incorrectly). Changed the router setting as suggested by the first test and subsequent tests show a few interesting things;
The primary doesn't change.
The ones listed as backup all have PTD in the name - so far I have seen 3 of them.
The results are inconsistent.
I use cable for internet and maybe have no control over this. Still have a lot to learn and any insights welcome.
You are probably using a cable modem, but to use the fixed DNS go to PCLCC network and set up your interface.
If its cable modem, the only detail you change is the line for DNS server address and set it to 18.104.22.168 or whatever address
If however you have a cable modem then you have a choice you can either leave the DNS address set in the router or
change the DNS address to the fastest server.
In my case I have a ADSL/router but turn off DHCP and use static addressing. Instead of using my router DNS I set the
nameserver to 22.214.171.124 which is fastest for me and linux reads this from /etc/resolv.conf
Changing DNS wont alter the speed of your connection, what it does is affect the speed of which domain name
e.g. google.com are converted into IP addresses e.g. (126.96.36.199)
If you visit an internet page that serves many different adverts then this page may apparently load faster as the time
taken to lookup each individual address is reduced.
