This is a cross post from another help forum that I made to someone who was having connectivity problems:
>>Sorry I didn't get home from work till 1 AM in the morning. Extra DNS is supposed to speed up your browsing by caching IP addresses thus allowing you to bypass the step of contacting the DNS server to resolve the host for the site you want to visit.
But in this case, another feature of ExtraDNS might come into play. Rather than the one primary DNS server and 1 backup server that the ISPs use to resolve the host, ExtraDNS polls up to 10 DNS servers simultaneously. Whichever one resolves the host first is the one ExtraDNS uses. The ISPs default is to poll the primary DNS server until it resolves the host, but if it cannot resolve the host the ISP polls the secondary server only after the primary times out. So if the connectivity issue is a DNS server problem (caused by a flood junk requests brought on by a Denial of Service attack) you would stand a better chance of finding a working DNS server using ExtraDNS.
ExtraDNS costs ~$20
(~$30 actually )as I recall but there is a 30 day trial.<<
Look at my last post in this thread from this forum for a little more on ExtraDNS and a link:
