Question 554 - 220-1101 discussion

Which of the following DNS records is used to look up the IP address assigned to a domain name?

SPF

Suggested answer: A

Explanation:

A DNS record is a data entry in a DNS server that maps a domain name to a specific value, such as an IP address, a mail server, a name server, or a text string.There are different types of DNS records for different purposes, and each type has a specific format and syntax12.

The A record, also known as the address record, is the most common type of DNS record, and it is used to look up the IP address assigned to a domain name. The A record maps a domain name to an IPv4 address, which is a 32-bit numerical value that identifies a device on the internet.For example, the A record for www.google.com is 172.217.14.20612.

The other options are not correct because they are not used to look up the IP address assigned to a domain name. The MX record, also known as the mail exchange record, is used to specify the mail servers that handle the email for a domain name. The MX record maps a domain name to a priority value and a host name of a mail server.For example, the MX record for gmail.com is 10 alt1.gmail-smtp-in.l.google.com12.

The NS record, also known as the name server record, is used to delegate a domain name to a set of authoritative name servers. The NS record maps a domain name to a host name of a name server that can provide authoritative answers for the domain name and its subdomains.For example, the NS record for example.com is ns1.example.com12.

The SPF record, also known as the sender policy framework record, is used to prevent email spoofing and spamming by validating the sender's identity. The SPF record maps a domain name to a text string that specifies the authorized mail servers and IP addresses that can send email on behalf of the domain name.For example, the SPF record for microsoft.com is v=spf1 include:spf.protection.outlook.com -all12.
