scott - i wondered if Dynamic DNS Updates is what you meant. :)

Currently DnDns doesn't support UPDATE. I've created a workitem to the DnDns portal as a feature request and added links to the two RFC's that apply:

Add Support for Dynamic Updates (DNS UPDATE)

Do you know if you need the OLD style UPDATE (insecure) or the Secure Dynamic updates specified in the newer RFC. I suspect which you'll need will depend on the DNS Server (either a configuration setting or a matter of it supporting the newer secure updates). Certainly the older style dynamic updates will probably be easier to implement...

I've briefly scanned RFC 2136 and it doesn't look too bad to implement on top of the current DnDns infrastructure.

I'm a bit bogged down right now with a few things, but I'd certainly interested in working on it eventually...

You're also welcome to take a stab at it if you feel comfortable with Protocols. :)

sorry for not making myself too clear (long day). what i need to do is get DNS update working. i have an embedded system that supports an ip port. DHCP is working fine on it. i want to get the newly established ip address associated with my chosen host name into the DNS server so that other machines can find the system. for instance, i want to be able to ping "HostName" instead of "10.1.0.1"

thanks,
scott

Hah, no problem...

Zone Transfers (AXFR) support has not been implemented yet. I've added that feature request to the CodePlex site here:

Add Support for Zone Transfers (AXFR)

I included the appropriate links to the RFC's, etc. I'm not sure when I'll be able to get around to it, feel free to jump in! :)

Absolutely kick-ass J! I've spent a lot of time getting my head around "talking DNS with C#". I got stuck in a couple of places and your DNS library has enabled me to accelerate my thought process significantly. Quick question - are you planning on supporting zone-transfer requests (unless I missed it in there)?

Thanks J (My C# hero of the month:)

this is good stuff. i have a need to implement stuff a host name into a dns server, but i don't do the protocols too well. can you point me in some direction that is a bit more language friendly than the rfc's?

thanks

That would certainly validate that the Domain portion of the email was valid -

I have also implemented an SMTP library as well but it's not in any condition to release. There is one out there called OpenSmtp.Net at http://sourceforge.net/projects/opensmtp-net/ - perhaps that will get you there.

Good article. Do you think one could validate an e...

Good article. Do you think one could validate an email address by querying the domain's mx record, would that be a good use case?

Maybe you could point me to the right direction, I need a smtp mailer for .net on w2k...

2008-02-04T20:39:00.000-05:00

My pleasure!

That's what initially got me started down this road. When real DNS support wasn't provided in .net 1.0 and 1.1 I just figured they'd get to it later....it's suprising Microsoft still hasn't implemented it in 2.0/3.0/3.5.

Perhaps there's not a huge demand...

2008-02-04T13:31:00.000-05:00

Awesome. I wrote just what I needed a few years ago to get MX records because you can't from the default .Net libs. Just MX was a pain in the rear, thanks for taking the time to implement so many!
