Forums Developers Advanced DNS queries

I want to query a dns server, and get MX records for domains and such.

Does anyone understand/know the dns protocol? I tried, but i cant figure it out. I think the best way to do it would be to code it into mirc instead of using com object(buggy unreliable etc) or a dll (none exists anyway)

I need this method to work on any computer(using ISP dns server), so using something like nslookup wont work. I need to code a dns client in mirc :X

Any suggestion or examples?

I think DNS is too-large a subject to answer in a forum. I suggest this site http://www.dns.net/dnsrd/ but you could also use your favourite search engine with "Domain Name System" as the key words.

Actually it would be something simple, maybe a few lines of code. it would be something like this

sockwrite dnsserver query=mirc.com querytype=MX

And the server would reply with the answer. I just cant figure out the syntax :X And yes ive tried google etc

hello, i also made a search on that and i found that it uses UDP.
So i whent to my Ethereal and put it snifing while in browser i typed www.sdfsd.fgfds.pt (since my browser and OS didn't know it, a query was sent). I can send you the log if you want but you can also check for your self if you get the program.

Have a good work on that
