I\u2019ve also seen folks use domains with a common top-level domain, like bwuchlab.com. As of this writing that domain is available for sale, so there wouldn\u2019t be any conflict or such if I started using it internally without registering the domain. I feel like this is a bad practice as someone else could buy that domain, I\u2019d have no control over it, but may have some documentation or screenshots that include that name. I prefer to use a name that I own. For example my internal DNS domain is lab.enterpriseadmins.org. I already own the domain enterpriseadmins.org and have control over who would get to use the subdomain LAB. If I wanted to create an external DNS host name of something.lab.enterpriseadmins.org, I could do that no problem and could even get an SSL certificate issued for that name if needed. I wouldn\u2019t be able to do this with a domain that I don\u2019t own.<\/p>\n\n\n\n
If you don\u2019t need\/want to own a domain name, another good option is to use a reserved name. For example, RFC 2606<\/a> reserves the names example.com, example.net, and example.org for documentation purposes. You could use them in your internal network without prior coordination with the Internet Assigned Numbers Authority (IANA). This works well as you can take screenshots and such for documentation where example names in screenshots work, for example:<\/p>\n\n\n\n Once we have selected the DNS names that we are going to use, we also need to figure out a way to get our clients to point at our DNS server for resolution. I don’t like pointing clients directly at my lab infrastructure for name resolution. Just like I mentioned in a previous post about Home Lab Networking<\/a>, I don’t want a lab problem to prevent the TV from working. There are a couple of options in this space, I’ve included a few options below with links to more information.<\/p>\n\n\n\n <\/p>\n","protected":false},"excerpt":{"rendered":" In previous posts we discussed considerations for building a Home Lab and for deciding on network ranges to use. Once we know the networks we will be using, its time to start thinking about services that will be required.
