- As for the speed issue, if you have a 19,200bps connection to an ISP with
- reasonable performance hardware, you won't be able to tell the difference as the
- DNS packet will make it round trip in about the same time as it takes to encode it
- to PPP and back again. If your using Web browser, where DNS is reasonable heavy
- useage, again you aren't going to notice because of everything else thats going on
- concurrently, assuming you have an intelligent browser.
-
- On a 9600bps connection, and pointing the Primary DNS to some location not on your
- providers network, there is a high probability you will get a resonse from a
- seconday server on the providers network before you see the response from the
- distant Primary, and you may or may not wait for the timeout or returning packet
- from that Primary depending on how one has the DNS layer configured for the
- specific requests.

- So does anyone have a good reason to connect to more than one ISP at a time ?
-
- Does anyone have more than 3 ISP accounts ?
