RFC 1918 defines the following IP blocks as designated for private intranets:
10.0.0.0 – 10.255.255.255 (10/8 prefix)
172.16.0.0 – 172.31.255.255 (172.16/12 prefix)
192.168.0.0 – 192.168.255.255 (192.168/16 prefix)
I think it’s about time we have the same thing for DNS, for example:
.dev
.intra
The logic is as follows.
.dev
for intranet based development instances of a site. For example this website’s dev instance on my intranet is robert.accettura.dev
.
.intra
for intranet url’s such as yourdomain.intra
. This can be used for any intranet purpose (internal homepage, email system, blogs, wiki, etc.).
This is a much more logical system than using intranet DNS servers to hijack a domain for internal purposes, or reserving subdomains for the purpose.
Someone should go pester ICANN about such a standard. Btw: .local
is stupid, if it’s local, it’s localhost.

Hmm, I’ve always used .local for stuff like this. Of course, I have a pretty small network. 🙂
