Get The Value Texts From The Webpage?

I tried to get the value text at the end of the field id equal text on the webpage at each line. I only want to get the two value text at each line which something is like this: 111.11.11.11:4000. I want to input them in the messagebox but when I clicked on the button, it displayed as "fieldid=fieldid2=". I am trying to make the project to check and get it response as like this 111.11.11.11:4000 but it got it wrong. The reason why I want to get do this is because when I get the value text with the full ip address and the open port to input the strings text on the messagebox, I can start the next method by writing the code to make the project connecting to the sever with an open port.

Here it the code:

Code:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
' used to build entire input
