DNS Troubles

No, that looks to be a DNS problem, it failed at 'looking up'. I'll drop support a note.

correct as usual Rik, just swapped to open dns and the forum loads fine but not with IDnet dns.

Thanks for the confirmation, Ted.

I have my primary DNS set to Idnet and the scondary to open dns, seems to work for me. Don't usually have problems accessing any sites with that setup.

Rik · Aug 24, 2008, 12:09:50

Interesting idea, Vit, I'd never thought to do it that way.

Sebby · Aug 24, 2008, 13:02:47

That's quite a good idea - thanks!

Ted · Aug 24, 2008, 13:06:03

Yes that does work but is slower that just Open dns, maybe because the primary IDnet server doesn't work and then it defaults to the secondary Open dns server?

Rik · Aug 24, 2008, 13:07:20

Slower generally, Ted, or just when there's an issue with IDNet?

I'd imagine that's how it would work, Ted, in which case it would be slow in the case of sites that IDNet's DNS fails on.

I just meant slower when trying to access that Toppy forum. With idnet=pri and open dns=sec there is a lag and with open dns =pri&sec it goes straight in (cache cleared first).

Rik · Aug 24, 2008, 13:12:35

Thanks, Ted.

It may be a little slower but I really can't be bothered changing dns servers all the time.

Rik · Aug 25, 2008, 10:52:56

It's like spring and autumn, when the temperature is on the borderline of short/long sleeves.

Sebby · Aug 25, 2008, 10:57:29

OpenDNS is pretty reliable. I'm not sure why I changed back to IDNet's in the first place come to think of it...

Rik · Aug 25, 2008, 10:57:50

Because you love us?

Sebby · Aug 25, 2008, 11:03:07

That was it.

Perhaps because for most resolves they are quicker.

Sebby · Aug 25, 2008, 11:05:21

Could have been, although OpenDNS is feeling faster for me now.

I recently tried Open DNS but didn't notice any difference.

Sebby · Aug 25, 2008, 15:35:40

I think it's much of a muchness with DNS, and perhaps the differences are only evident when there's a problem with one of them.

Rik · Aug 25, 2008, 15:40:31

Technically, IDNet's ought to be faster when everything is working normally, as it's within the network.

Sebby · Aug 25, 2008, 15:41:39

That's true, Rik.

Rik · Aug 25, 2008, 15:43:09

Mind you, that assumes you can measure a few milliseconds in everyday use.

Sebby · Aug 25, 2008, 15:45:26

I think that's the key point. OpenDNS certainly seems to be more reliable, so even if it is costing me a few milliseconds, I'll probably just stick with it this time.

Great idea. If the primary DNS fails for a particular site, how long is it before the query is resent to the secondary DNS? Is it many seconds, just a few, or milliseconds? I've no real reason for asking other than an interest in how it works.
