I want to share another domain buying tip (two actually), which might seem totally obvious, but you wouldn’t believe how often I don’t adhere to these when I buy domain names.
The primary piece of advice is to set up default nameservers at your preferred domain registrars. Most companies will allow you to set up default DNS in your account control panel, and this will ensure all newly registered domain names are set up to your preferred DNS. Assuming you plan to park the domain names, at least temporarily, you will be able to use your parking company’s DNS.
Once you have secured the domain names in your account, you will want to remember to add them to your parking account. It’s a nice time saver to not have to wait until the names show up (refresh, refresh) and then click around to change the DNS, but it does you no good if the domain names aren’t added to your account. Your parking company may be happy, but you won’t earn anything nor will you be able to field purchase inquiries.
If you are looking to sell the domain names at an aftermarket company, and you don’t want to park them there, be sure to add them to those accounts at the same time. In the past, I had not really done all of these steps at once, and if I didn’t do them at the time of registration, the likelihood of doing them later is slim.
