When I make the following call:
IPHostEntry hostInfo = Dns.GetHostByAddress( hostIPAddress ) ;
If the PTR (i.e. the IP address to name resolution) does not exist my
program will start making Netbios calls (Name query to the remote host).
The netbios lookup is very undesired.
Is there a way to not perform the netbios query if the PTR record does not
exist?

I wrote a method which takes an ip address and returns hostname as shown below.
It works fine.. only problem i have is when the passed ip address is not
found in the database the method throws this error message :
The requested name is valid and was found in the database, but it does not
have the correct associated data being resolved for
How can i prevent this error message and instead return "-" ?
Many Thanks.

Hi!
I have a problem with
System.Net.Dns.GetHostByAddress(ls_Request.UserHostAddress()).HostName
Usually the call GetHostByAddress returns the correct hostname of the
client, but sometimes I get a hostname like _CERDR1342B88E.
Why? The clients are running under Windows CE.NET 4.1...

I have a class for logging information about user activity on a web site, but
it suddenly became really slow. I was wondering what factors may have
caused the slow down.
Initially, I used the following code:
ul.HostName = context.Request.UserHostName;
Since the UserHostName is not always resolved, I opted for the following
more effective code:
IPAddress hostIPAddress = IPAddress.Parse(context.Request.UserHostAddress);

I can type an IP address and receive Internet domain name and my workstation
name however no other IPs of computers on our internal network will resolve
to a thier machine name only to the same IP that is entered. What's up
Microsoft????
I can say that before we switched over .NET 1.1 to 2.0 the
Dns.Resolve(entry); would find a name for any IP, LAN or WAN.
Q. Any ideas??????????

DNS.GetHostByAddress runs very slow for foreign IPs.
I heard that DNS.BeginResolve can make asynchronous IP to Host resolve.
Can anyone provide me an example of VB.NET code that would make asynchronous
DNS.beginResolve call?
I need it to make a try to resolve the IP to HOST and to quit if it's taking
longer than 5 seconds.

I am trying to get the DNS name of an arbitrary IP address on the network.
If I use GetHostEntry as the documentation suggests I only get the name of
the machine I am running the code on. All other IP’s returns the IP in the
HostName property of the IPHostEntry object returned by GetHostEntry.
If I use Dns.GetHostByAddress or Dns.Resolve I get the name, but these are
marked as obsolete. What is the correct way to get this...
