Which type of DNS record contains human-readable text information?

1. SPF

2. TXT

3. SOA

4. AAAA

The correct answer is: TXT

The type of DNS record that contains human-readable text information is the TXT record. TXT records are flexible and can hold a variety of textual information related to a domain. They are often used for purposes such as providing additional data about a domain, including verification of domain ownership and email security. For example, they can include information for SPF (Sender Policy Framework) as well as other applications like domain verification for services such as Google Workspace or Microsoft Azure. SPF records are a specific implementation of TXT records intended to prevent email spoofing by defining which mail servers are permitted to send email on behalf of a domain. However, SPF itself does not encompass all human-readable text information but rather serves a specific function within the broader capabilities of TXT records. The SOA (Start of Authority) record contains administrative information about the domain, such as the primary name server and contact email, but this information is not typically considered human-readable in a broader context. The AAAA record is used to map a hostname to an IPv6 address and does not contain textual information intended for human readability. Thus, the TXT record stands out as the correct choice, primarily due to its purpose and versatility in hosting various types of human-readable text information.
