Greetings everyone, 👋
I'd be happy to work on this issue.
I'm new to this project and I just started learning rust to contribute here. I hope this will be a good starting point for contributing.

Can I take this up? I'll also be glad to be guided a bit.

[TheBlueMatt]

Sure, this is basically as simple as adding a new variant to the NetAddress type.

[ritikramuka]

I am completely new to this so could you provide some more details. I am unable to figure out where to add this new variant to the NetAddress type.

[TheBlueMatt]

Just take a look at how the existing variants work (eg OnionV3, etc) and add a parallel one for DNSHostname :). More guidance than that and I'd just write the code.

Hey @ritikramuka 👋🏼
I started checking out this issue but I didn't write anything. I just pushed some code maybe we could see it together as is my first issue too. What do you think? :)
