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...

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...

caused the slow down.
Initially, I used the following code:

Since the UserHostName is not always resolved, I opted for the following

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...

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
