[DNS] Fastest DNS Server?

Hello everyone! I live in Pennsylvania and have Comcast. My current DNS servers are 68.87.75.194 and 68.87.64.146. What is the fastest DNS server that I can use? Thank you!

I also use openDNS, and I love it. Seems very fast to me.

If you want to test the responsiveness of servers to compare, you can use my ns_bench program to test the servers. The ping to a NS server is not a good indication of how fast the query responses will be for a nameserver.

I use 4.2.2.1 and 4.2.2.2

I don't really care for OpenDNS that much and 4.xxx is in Chicago (Level 3/Verizon/ DNS servers which I ping like 15ms to, and they never go down.

Unlike the POS Comcast DNS is.

Edit: I believe 4.xxx once entered in for your DNS it will automically connect to the nearest city to you.

The GTEI servers (4.2.2.x) are anycast I believe, so you should ping relatively well to them from most areas.

quote:
PING 4.2.2.1 (4.2.2.1): 56 data bytes
64 bytes from 4.2.2.1: icmp_seq=0 ttl=52 time=10.288 ms

I'm in Delaware, so I'm obviously not pinging 10ms to a server in Chicago

I have tested the Comcast DNS servers, Level 3 DNS servers, and OpenDNS DNS servers. The results seem to be slightly different each time I test them, so I have decided to show you the results of three different tests.

Comcast Test #1

Nameserver              Response Time (ms)
                        min/avg/max/stdev/retries
68.87.75.194            10.05/13.24/22.52/4.71/0
68.87.64.146            19.02/20.51/22.10/1.17/0

Level 3 Test #1
Nameserver              Response Time (ms)
                        min/avg/max/stdev/retries

4.2.2.2                 15.35/20.30/36.00/7.87/0

OpenDNS Test #1

208.67.220.220          16.09/16.61/17.41/0.43/0

Comcast Test #2

68.87.64.146            18.59/19.87/21.59/0.98/0

Level 3 Test #2
Nameserver              Response Time (ms)

4.2.2.2                 17.13/19.74/28.57/4.43/0

OpenDNS Test #2
Nameserver              Response Time (ms)
                        min/avg/max/stdev/retries

208.67.220.220          16.44/19.80/31.47/5.85/0

Comcast Test #3

                        min/avg/max/stdev/retries

68.87.64.146            18.63/19.81/21.04/0.97/0

Level 3 Test #3
Nameserver              Response Time (ms)
                        min/avg/max/stdev/retries
4.2.2.1                 17.62/21.03/24.19/2.64/1
4.2.2.2                 15.58/16.67/18.47/0.96/0

OpenDNS Test #3
Nameserver              Response Time (ms)
                        min/avg/max/stdev/retries
208.67.222.222          16.25/21.79/35.52/7.42/0
208.67.220.220          16.46/17.15/18.22/0.76/0

I have calculated the average response time of each DNS server test.

Comcast Average
68.87.75.194 - 11.97 ms
68.87.64.146 - 20.06 ms

Level 3 Average
4.2.2.1 - 21.30 ms
4.2.2.2 - 18.90 ms

OpenDNS Average
208.67.222.222 - 19.01 ms
208.67.220.220 - 17.85 ms

It seems that 68.87.75.194 is the fastest and 68.87.64.146 is the slowest. Can I make my computer only use 68.87.75.194, or do I need two DNS servers? If I need two DNS servers, can I use 68.87.75.194 and 208.67.220.220? Thank you!

lol, your not going to see any difference in that short of a ping time for all of them.

I wouldn't recommend staying with comcast dns...but that's just me.

68.87.75.194 is my primary DNS server and 68.87.64.146 is my secondary DNS server. What is the point of having a secondary DNS server, and is it required to have one? Thank you!

Yes, I do not understand why you actually need both?

Put it this way - would you rather browse a little more slowly due to timeouts on the primary DNS or not browse at all because you can't look any hostnames up?
