Really slow dial up internet connection... mainly DNS Resolution... I think

jimdaworm · 12-11-2003, 10:33 AM

I have setup my resolve file with my ISP at the top
wanadoo.es then I have two DNS server IP addresses that were on my ISPs web page. Somtimes it seems really really slow to resolve pages...

Is there anything else I can do to speed it up?? Somtimes its ok but sometimes its really bad like takes about 20secs to resolve an address.

Sounds more like a lagged DNS server to me...

One thing that people misunderstood quite a lot is role of DNS servers. Many assume that the Internet will only work if they use their ISP's DNS servers only.

The fact is you can use any DNS server you want, as long as it can resolve hosts properly for you. So try to pick one (or two) that is consistently fast, and use it.

I think it might have had somthing to do with a firewall script I installed too... I dunno I took it out and am trying Firestarter it seems to be faster (I know I should make my own but I am on a steep learning curve as it as at the moment!)

Can you recommend a good place too find fast DNS servers... I was serching on the net the other day as someone told me you could use DNS servers from anywhere but couldnt find any....

I might just try looking up some competitor ISP details and using their DNS for now!!

Thanks again!

Well, my preferred method is to find a site you visit always... and then dig thehost.tld... eg.

:

Code:

mothugz@slackbox:~$ dig linuxquestions.org

The bolded parts are the NS servers for LQ... to resolve those hostnames to IP addresses, use the nslookup command. And before you actually use the NS servers, try pinging them and see the reply time, avoid those that are slow. For best results, use NS servers that are closer to your geographical location.

Disclaimer: I'm not telling you to use LQ's NS servers... the above is just an example
