This library prints ip addresses to stdout if they are ipv4 after listening. it does this by calling os.networkInterfaces(), which now returns 4 or 6 (unlike before in v17 - family <string> Either IPv4 or IPv6).

Environment Versions

1. OS Type - any
2. Node version: $ node --version: v18.0.0
3. http-server version: $ http-server --version present in latest master -

   http-server/bin/http-server

   Line 229 in 318c55f

   if (details.family === 'IPv4') {

Steps to reproduce

1. install node 18
2. start server

Expected result

server prints:

Starting up http-server, serving ./
Available on:
  http://127.0.0.1:8082
Hit CTRL-C to stop the server

Actual result

server prints:

Starting up http-server, serving ./
Available on:
Hit CTRL-C to stop the server

Other information

I think the library should take into the current value of process.version when printing listening interfaces. Better yet would be to not check this at all. why not show the user (properly formatted) ipv6 links? I will submit a fix that replicates the old business logic, the new business logic could be considered in a different ticket.
