Strange IP address format?

[bonedoc]

I am using:

Dim h As System.Net.IPHostEntry = System.Net.Dns.GetHostEntry(System.Net.Dns.GetHostName)
lblIP.Text = h.AddressList.GetValue(0).ToString

to get my IP address. I am getting this format returned:

2002:450d:a56c::450d:a56c

I guess this is IPv6 format? I am doing some TCP stuff, and every time I try to connect, I get the error "no such host known". Is there a way to connect differently with this format or convert it? What is strange is when I go to canyouseeme.org, it gives me a normal address. Sorry..I am in the wrong forum as usually..

Here is how I get the address:

Dim h As System.Net.IPHostEntry = System.Net.Dns.GetHostEntry(System.Net.Dns.GetHostName)
Dim address1 as string = h.AddressList.GetValue(0).ToString())
Here is how I am trying to connect:
Dim tcp As New TcpClient
tcp.Connect(address1, 800)

Is there a way to connect to an IP by its website or DNS name?

One of the overloads for the Connect() function takes the dns name for the host you want to connect to:

Dim t As New TcpClient()
t.Connect("www.yahoo.com", 9999)

Hey, nice to see someone from Kansas here! What if there is no DNS name? What if it is straight IPv6?

You can try the IPAddress.Parse() method.? This method will return an IPAddress object.
I don't know if it supports IPv6, but you can try.
Try:

t.Connect(IPAddress.Parse("ipv6 address string"), port)

IPAddress.Parse supports IPv6 format the documentation states.

Ok, so I am doing the IPAddress.Parse(IPAddress)

Now, I get the error:

"An address incompatable with the requested protocol used"

So, I tried doing:

Dim tcp as New TCPClient(System.Net.Sockets.AddressFamily.InterNetworkV6)

But I get the same thing. What could I be doing wrong? When my computer accepts a connection with a tcpListener, is there a way to get the requesters IP and/or Address type?

Well, that makes it at least say "The host actively refused connection", rather than "no such host exists". I can't see why it would reject it if the port and IP are both correct...especially if it sends fine, but does not recieve...Ahhhh

Either your machine, or the remote machine has a firewall that is denying the conenction, or the service/tcp stack of the machine has been instructed to deny your connection (or maybe a range of conenctions you fall into)
