Query DNS
I would like to query the DNS server for the MX record. In other words I would like know the mail server IP address in a domain. Some sample code please...
jkr
Which OS?
ASKER
Both Win 95 and Win NT
Which O/S for DNS, NT also?
ASKER
An unknown host for DNS. I want to write a program which will make a zone transfer from a given domain which includes all the entries in that domain.
for example i want to perform a zone transfer from microsoft.com or cnet.com
thanx for the support

This question has a deletion request Pending
This question no longer is pending deletion
Sad,
I'd like to see answer myself.
I do not object to the delete request, but hope it gets reposted, perhaps in unix/linux networking or TCP/IP area. Enquiring minds want to know.
You can surf and find both code and shareware and freeware that may purport to satisfy you original question. I have seen some work and some not. I think/suspect it is mfr dependant.
For your subsequent 'i want to perform a zone transfer', again, I suspect this is beyond our scope. The folk you want to transfer from 'should' be allowed to only transfer to people they 'like', servers they 'trust', meaning they need to control their own resources, and not quickly give you permission to tie them up with needless work. I hope you know what I mean. If you want resources from Microsoft, you should ask.
For DNS lookups, I've seen these work and not work, and, perhaps like you, I'd like to know the difference, like why? Perhaps it all works better if everyone runs unix, perhaps vendors add incompatibility tweaks. That's why I'd like the comments to continue.
But, as they dried up here, I can understand your desire to move on.

SunBow,
I didn't understand what you tried to tell. Before that, thanx for the interest that you have shown in my question. Why i gave the request for deleting this question is I didn't find any one showed interest in my question.
The reason could be like you said may be beyond our scope. Let me fight. I know how the systems operate using raw sockets with udp. I observed certain DNS querys while I am using the Network Monitoring Tools.
I thought some or the other might have some documentation. But, the situation is not like that. I am trying to browse through rfcs for these DNS querys. A DNS query is nothing but a zone transfer. I think i can get it with in 2 days. I posted this question around a week back. As i said there not much response. I will post this same question with an answer once again. Any way thanx for your support.

Right, I understand delete request, it looked rather boring.
I am not an expert on this topic, but I do have a part time interest in it to assist in viewing integrity of my corporate network, ie, not musch interest beyond the firewalls, real world networking. So pardon some of my misconceptions.
I have used network tools. I once had a windows tool to so pings and tracert's that was wuite flexible and had menu items for the various DNS records with which I am not all that familiar. Most either did not work or GPF'd (like the tool could be at fault - but I had heard that record availability may vary depending on plaftform). A former coworker had a tool that easily displayed the records, but I think it was vendor specific - the tool went with the server.
I may have misunderstood your 'transfer' to mean to gather the entire hierarchical table, or at least one of its zones. That sounded time consuming (traffic).
There are a number of programs available to do similar 'monitoring' or queries, shareware and freeware, and some $$$$ that allow a temporary (time-expired) use of product for demo. Some containing source code, while most seem to want parts remaining as .dll's etc.
I intend to return to checking the 'net for further info and source this week, beginning with getting some access to Visual Studio to put things together.
I'd prefer another kind of networking topic to address issues like this (UDP, TCP, etc) rather than just by operating system. But for monitoring, I'd like to see all packets, not just UDP, to best get a handle on all that is on the wire, hopefully by category, even application some day.
I am not sure what you mean by "I will post this same question with an answer once again", if you have answer, I'd be happy to hear. I'll leave it now.
Perhaps I'll get opportunity to eXchange with you here again. Would be nice.
Deleting this one is fine by me.

SunBow,
Thanx for your support.
Actually I am looking for some source code. But still It helped me.
