Solved DNS Server - use any one that "ranks" higher?

[jimnycricket]

During the internet access outage, I allowed Windows 7 to diagnose and fix my issue. I did read an error message about DNS and started poking around and found a DNS Benchmark freeware which gave me list of DNS Servers which rate higher than the one that I am currently using. Question - can I use any DNS for my network and is there advantage or disadvantage?

 

[Shadowjk]

Not sure what you mean by one ranked higher than another. Is it linked to response times?

It depends on what you are doing as to what type of DNS server is best. If an organisation then you may want to use an internal DNS server so that internal host names are resolved. You can either set one up normally or you can point your DNS server to your default gateway and your router should use it's internal one. For public DNS servers I normally use Google's Public ones rather than my ISP since Google has a much higher throughput and better failover capability.

Google DNS :

8.8.8.8

8.8.4.4

Of course it is best to set these up on the router so all clients use them rather than going to each host and assigning them.

Hope This Helps,
Josh

Yeah, I was talking about response time. I found 4.2.2.1 and 4.2.2.2 to be higher ranked in response time according to DNSBench.exe freeware. I made the change in the router.

My Question is that the ISP Provided DNS cause internet outage where I need to reboot my router?

 

[Shadowjk]

Nope, DNS should not affect the stability of a router. If you have to reboot the router to enable connectivity then you are probably looking at either an issue with your connection or a possible hardware issue.

I stumbled across the DNS Benchmark webpage and liked what I read . I ran the DNS Benchmark program to find the fastest reputable DNS servers and subsequently changed my TCP/IP protocol properties to "Use the following DNS server addresses:" from "Obtain DNS server address automatically." I also changed "Obtain an IP address automatically" to "Use the following IP address" and entered my DSL modem default IP addresses for IP address, Subnet mask, and Default gateway. I didn't notice any faster website surfing. I did notice after several subsequent reboots that I was accumulating errors in my Windows Logs related to the network. So, I changed the IP address and DNS address items back to the default "Obtain automatically" setting. All the Windows Log errors didn't appear anymore.

My ISP is Verizon DSL, so your mileage may vary.

The lesson I learned was that if it ain't broke, don't fix it.

This is for work/office setting with about a dozen station and dozen VOIP phones; so I need to have the internet up 100%. I have frequently had to reboot the router. The router is acting as my dhcp server and assigned an internal IP address of 192.168.10.1 and is set to obtain IP address automatically. Computers are set to obtain IP address automatically also.

Your IP configuration shouldn't be an issue. When the Internet disconnects are you able to ping each device within the LAN or does all connectivity fail?

Do you have any lights on the router? Upon disconnect does the Internet light change colour at all?

Many thanks,
Josh

I haven't pinged devices within the LAN when the internet goes down; rushing to restart the router and get the internet up and running. Same goes fro the lights - I am in a rush to get the internet up and running.

hmmm... do I do this on each of the computers?

 

[kado897]

Yes it only works at the computer level I'm afraid.

ofccourse all the logs error dissapear -you have the dhcp enable and you should never have to change the -optain an Ip automatically - instead you should use the first two ip to and paste them to use the following dns - ussually there is no visible prove that the speed increase ,but the answer - means the most near server you can access more faster.Don't forget also to change the QOS limit bandwith -going from 20 to 0

I'd like to add my two cents in here about the DNS Servers. As someone who messes around a lot with networks, due to being in a Cisco CCENT class, I'd have to say that I suggest using Google DNS or OpenDNS over anything else.

My local ISP uses their own DNS servers, which are poorly maintained.

Google DNS IPs

OpenDNS

I use OpenDNS on my personal server network, and GoogleDNS on my home network.

Can you comment more on QOS limit bandwidth?

Thanks for the reply.

I changed just the DNS IP addresses in the TCP/IP Properties on my network connection on my desktop to the Google DNS. I'll watch the Windows Logs for errors or warnings.

Please explain the QoS settings. I see an upstream and downstream on my DSL router page.

Is just changing the settings on your desktop or laptop network connection sufficient?

I also checked my Verizon DSL modem webpage, @ http://192.168.1.1/, and I noticed there were different DNS IP addresses configured. In order to fully take advantage of the DNS IP address change, don't you need to change the configuration settings on this gateway?

How do I find the modem IP address to make changes if necessary - like the DNS?

Do an ipconfig /all and look for your Default Gateway and DHCP Server IP address under your Ethernet adapter information.

Then type that IP address into your browser address. My DSL provider is Verizon. I get the DSL modem or Gateway setup page where I can view status and change settings.

I hope this helps.

ipconfig /all gives me the configuration information for my router not the cable modem.

 

[tjg79]

In my case, my router and DSL modem are one and the same. Do you have a separate router and modem?
