There should be an A record configured for the root of the domain as well as the www subdomain. An A record can then be configured for any other subdomain of the website such as blog.

For example, deals. This is most often used by SaaS tools to verify domain ownership. The tool can generate a unique piece of text, and the domain owner would add it to the domain's DNS record in order to verify ownership.
SPF or Sender Policy Framework is an anti-spam system designed to indicate at a domain which mail servers are authorized to send email on behalf of a domain. When a receiving mail server receives mail from a server other than one specified in the domain's SPF record, it can choose to reject the mail or send it to the spam folder.

A domain can have multiple MX records and most domains have at least two MX records for redundancy. MX records are labelled by priority, with 0 being the first MX record to be connected with and the other MX records with a higher number for priority will be connected to if the other MX records cannot be reached.

Regular DNS doesn't have the ability to search the right-hand side of NS records and then return all matches found, only passive DNS databases with wildcard search functionality can perform that sort of "magic" for arbitrary name servers of interest.
For instance, consider Didn't the earlier "A" record example in this article show www. The answer to this question is that multiple domain names may be configured to point at a single IP address via "A" or "AAAA" records, while PTR records will normally only return one of those domains.
So what are the "top seven" DNS record types? Let's go through my picks… 1 "A" Records: These records map domain names to traditional IPv4 "dotted quad" addresses. For example: www. An example Quad A record: www. For example: ucla. There are a couple of surprising things about PTR records.
As you can probably guess, a TXT record is simply a text record.
