VB and VB.NET are different languages. But yeah, Delphi ran circles around VB in nearly every measurable way. I don't think anyone would seriously argue that VB6 was a better language nor had the better tooling. And earlier versions of VB would have only compared even worse.

As for what libraries VB had for networking, there was some HTTP OCX that was bundled with Internet Explorer (and I don't mean the Trident renderer), which was awful. But aside that, there was only a basic wrapper around the Winsock C libraries. To be fair, the Winsock OCX was pretty decent fot what it was, but you were left to write all the host layers (OSI) for yourself.
