DNS problem

Sometimes my browser intermittently says it can't find a site / sites. I believe my ISP is not resolving the IP address from the domain name quick enough / at all. Repeatedly hitting "reload" will get these in the end, but it's annoying (obviously) There is software that will cache IP addresses locally - any recommendations?
Or have I got the wrong idea?

I agree with NachoMahma. Try using OpenDNS. If you can't get to the site here are the basic instructions for XP:

1. Select Control Panel from the Start menu.
2. Click Network Connections from the Control Panel choices.
3. Choose your connection from the Network Connections window.
4. Click Properties button.
5. Select Internet Protocol (TCP/IP) and click Properties.
6. Click the radio button Use the following DNS server addresses and type in OpenDNS addresses in the Preferred DNS server and Alternate DNS server fields.

The nameservers are 208.67.222.222 and 208.67.220.220.
. If you go to the advanced settings, you can specify OpenDNS (or other) as tertiary and quaternary DNSs. If the primary or secondary DNSs (ISP's) are unable to do the lookup, OD catches it.

You're advising I use those DNS servers? I'd like to cache IP addresses so that I don't have to use DNS look-ups for every-day things like Google. L

. You are looking for a caching DNS proxy. I had to run one for a while (don't remember which one) when my ISP had problems.
. BTW, if it's just a few sites, you can use HOSTS, but it doesn't update if a site's IP changes.
. And try adding OpenDNS to your list of DNSs

Don't really know about this?

(where's frollard when you need him..?)
your local in-computer dns cache lasts...I forget how long (network college in 2002...) anyhoo - if you're getting bad data from the dns - or your own cache, try in the command prompt one time fix: ipconfig /flushdns It will dump your local dns, and the first visit to each site will try at least once to resolve. I agree 100% with dilandou to try OpenDNS.

Thanks, I'll try the OpenDNS then L
. There are multiple solutions. . If you only visit a few sites, you can edit the HOSTS file (I have entries for Ibles, Google, &c commented out - I can just uncomment if I need to) . Adding a free DNS (eg, OpenDNS) to your list of DNSs to use will give you a backup when your ISPs DNSs don't respond. Open access DNSs are usually slower than your ISPs, but much better than nothing. . I'll do some digging around and see if I can figure out which proxy I used. It worked very well for me.

I'm not familiar with HOSTS, but I could probably look it up. Yes, a proxy that works is better than one that doesn't.

hosts is a 'permanent' on-computer file (named hosts, ironically, no extension - plain text file - edit with notepad) in the system32\drivers\etc folder Each entry is a name, with standard widcarding formatting, or ip addresses... you can add common entries like localhost 127.0.0.1 (not necessary as its already built in, but an example) www.google.ca 123.123.123.123 etc etc etc
*and I'm at work...surprising I missed this question - about 5pm...weird.

Thanks, but I don't want to Google it, I'd like for someone to recommend something they know to be good - what did you use?

you get Kate Bush...

I feel an obligation to at least answer at root level - even though my answer is commented below :P what os? what isp? what type (dialup, isdn, wireless, adsl, cable, fios...etc) DNS should cache locally already - for a decent amount of time. If your cache is shot, use the (from the command prompt, in windows xp++) ipconfig /flushdns I agree with dilandou's instructions on using opendns if your isp's dns is crap.
