In A Custom Domain Setup, You Have Your Job - And The Registrar Staff Has Their Job

Setting up a custom domain for your Blogger blog is pretty simple, when you follow the rules. All that you need are "A" and "CNAME" referrals, redirecting to Google servers.

Some bloggers, when troubleshooting a custom domain problem, get confused, or frustrated, and try tweaking additional settings. Such attempts won't help, and will only make their job, and the registrars job, harder.

• In specific cases, you may make changes to "MX" records. But "MX" record changes won't solve any problems with your custom domain.
• You may end up setting up a "TXT" record - if you must prove domain ownership.
• If you are setting up your own DNS server, you may change or create "NS" records using your registrar's CPANEL utility.
• If you're using registrar supplied DNS hosting, the "NS" records are the responsibility of the registrar.
• You have no need to create or change "PTR", "SOA", or similar records.

You do your job - and let your registrar do theirs.

Please, know your responsibilities, and the limitations of your responsibilities.
