Internal Link Format On Static Site

[chrisat1]

I’m building my website in a home based web server. As I have started to create internal links I’m wondering what the proper way of referring to the machine. 
Do I use the internal up address, local host or the outside domain name when referencing the root? What is best practice here?

 

example.com/things

localhost/things

192.168.1.99/things

You should omit the domain altogether. Preceding a path with a slash will make it relative to the website's root:

<a href="/things">

If you need to access your site from a different website you should put it on a public server.

From within pages under the same domain name, yes, do what Ingolme said. If you're hosting multiple names (virtual hosts approach), use the FQDN or fully qualified domain name (i.e. the whole thing: http(s)://www.somesite.com/things)
