Webhosting sites like wordpress or godaddy have several subdomains like https://hello.wordpress.com/ . Does each of them have a unique IP-address (v4 or v6)? If not, how does routing work?

I just checked and the output from host hello.wordpress.com equals host www.wordpress.com. So I assume that...

• www.wordpress.com resolves to e.g. 192.0.78.12/ and
• hello.wordpress.com resolves to e.g. 192.0.78.12/hello or similar.

Is this assumption correct?

You have an A record for each subdomain, so you can point it to the same IP address or a different one.

The routing of the sites is just done with the server configuration, I can't speak for GoDaddy or WordPress as I don't know what stack they are using.

I believe a standard Apache server would have the main domain in /public_html and the subdomain in a /sub.domain.com folder.
