A domain name exists on the internet only when a DNS server is able to give
an IP address.
Hi Francois,
Thanks for that, but what about detagged domains? The domain exists, but
doesn't have a registrar / DNS server associated with it. Is there any way
to tell the difference between a domain
A domain name can't be used if there is no DNS server delivering IP
addresses for it.
Of course it can exists on paper but it is of no use to access any
service.
Hi Fancois,
I suspected as much. However, in this case, the existence of the domain on
paper is also important - the purpose of

WHOIS shows the reserved domains owners perfectly. But some ICANN approved
comanies such as Dotster and Godaddy offer privacy option which prevents
the display of owner data such as name, address, and email.
That sounds ideal for my purposes. I don't need to know who the domain is
registered
I've done a little (so far) poking around in the relevant RFCs, and making
the actual query looks relatively straight forward. What I'm not sure about
is what server(s) to query? To date I've only every used web based services
like samspade or whois services hosted by domain registrars, so
Which leads to the obvious question of how to make a whois query
programatically.
I did an ICS Whois component a few years ago:

For COM domains, it does a double lookup to return Whois from the actual
registrar. But you do have to choose
Which leads to the obvious question of how to make a whois query

Michael, Angus, many thanks for the info - much appreciated! I'll take a
look at it tomorrow and see what I can come up with.

Hello Ja,
Is DNSLookup with WSocket async?
yes.
please dont reply to a thread if subject is different. Many modern
email reader can sort on thread so many people will not see your
question if they are not interested in the thread (in this case

Hello Francois,
Strange after all these years I did not check the AHostName before
calling DNSLookup for the first time :)
Anyway there is something I wonder. First exception is raised, then
TriggerDnsLookupDone is called with the right argument, however because
the exception it is never called,
