Is dnndev.me safe for local development?

Local DotNetNuke Development

When developing DotNetNuke on your local machine, it can be easier to use the domain dnndev.me or anysubdomain.dnndev.me. The official DNN instructions call for this setup.

Safety? Do they see my traffic?

It's safe.

No, they cannot see your traffic.

DNS resolution

The Domain Name *.dnndev.me simply resolves back to 127.0.0.1 - in other words, when your browser does a request for funkychicken.dnndev.me, it goes to your DNS service and the DNS service tells you which IP address to send you to. Everything at dnndev.me is set to point to 127.0.0.1 - which is always your local machine's IP address.

Once your browser knows the IP location of dnndev.me, it will send all future requests to 127.0.0.1.
