Subdomains Locally

I am running an application that uses subdomains, how do I work with this locally?

I don't want to buy a domain or fake one out.

SmartLogic has a domain that has two DNS records set up for this purpose. sldev.me has a wildcard record for subdomains and the domain itself, they both point to 127.0.0.1.

If you've used lvh.me in the past, this is similar but controlled by SmartLogic.

See below for examples on how to use it.

Naked Domain

$ dig sldev.me

; <<>> DiG 9.16.16 <<>> sldev.me
;; global options: +cmd
