.local is generally reserved for Avahi/Bonjour. The simplest case is say your computer name is "mypc", then on another machine on the same network, you can access that pc via "mypc.local", assuming you have public services running on it.
If you're just wanting a domain to use within your local network, I would refrain from using .local so that it doesn't conflict with this. I personally use ".lan" for stuff local to my network, but that's also not best practice.
Ideally, you'd own a real domain, for instance "mydomain.com", then use something like "*.lan.mydomain.com" for local network stuff. You can still use a local bind so nothing is public but you can guarantee that you won't conflict with anything else that way.
