Possibly your ISP's DNS server is trying it, and not all of the Internet infrastructure can deal with it yet. Maybe, who knows... but I think EDNS will interfere with many other sites, not just one :-? OTOH, what the OP is experiencing I also have suffered from time to time.

I just don't know what to check for next. There is no other website I have this problem with. Rather than using host, try using nslookup, but don't use it in the same way you're using host. Instead, type nslookup by itself to enter its command shell. From there, when you perform a lookup, it will tell you which server it's querying to obtain the answer. it...@mybox:~$ nslookup www.trade2win.com Server: 10.10.2.25 Address:10.10.2.25#53 Non-authoritative answer: www.trade2win.com canonical name = panna-229.trade2win.com. Name: panna-229.trade2win.com In my example, my box is querying my internal DNS server on 10.10.2.25 to obtain the answer. Run the same query against your local host multiple times to see how persistent the problem is. Once you've done that, switch to query against a separate server and run the query against it multiple times. server 4.2.2.1 Default server: 4.2.2.1 Address: 4.2.2.1#53 www.trade2win.com Server: 4.2.2.1 Address:4.2.2.1#53 Non-authoritative answer: www.trade2win.com canonical name = panna-229.trade2win.com.

Name: panna-229.trade2win.com Address: 208.43.120.229 Note that I'm querying for www.trade2win.com here and we're getting non-authoritative answers. To get an authoritative answers, we need to query for the domain name followed by a period. Not only that, but we need to set our query type to any. set type=any trade2win.com.

Authoritative answers can be found from: What the heck? We're returned to the nslookup prompt without it telling us where we can obtain authoritative answers. What's up with that?? Let me try my own internal DNS server. server 10.10.2.25 Default server: 10.10.2.25 Address: 10.10.2.25#53 trade2win.com. Server: 10.10.2.25 Address:10.10.2.25#53 Non-authoritative answer: Name: trade2win.com Address: 208.43.120.229 trade2win.com nameserver = dns3.registrar-servers.com. trade2win.com nameserver = dns1.registrar-servers.com. trade2win.com origin = dns1.registrar-servers.com mail addr = hostmaster.registrar-servers.com serial = 2008080808 refresh = 10001 retry = 1801 expire = 604801 minimum = 3601 trade2win.com mail exchanger = 50 aspmx3.googlemail.com. trade2win.com text = v=spf1 mx ip4:64.78.0.0/18 include:sfarm1.com include:aspmx.googlemail.com ~all Authoritative answers can be found from: dns3.registrar-servers.com internet address = 72.34.41.47 dns1.registrar-servers.com internet address = 74.81.64.51 That's more like it.
