What type of DNS resource record maps an IP address to a fully qualified domain name (FQDN)?
What type of DNS resource record maps an IP address to a fully qualified domain name (FQDN)?
The DNS resource record that maps an IP address to a fully qualified domain name (FQDN) is the PTR (Pointer) record. The PTR record is specifically used for reverse DNS lookups, where the goal is to find the domain name associated with an IP address. This is the opposite function of the A record, which maps an FQDN to an IP address.
Correct answer is PTR help.return path.com
A pointer (PTR) record is a type of Domain Name System (DNS) record that resolves an IP address to a domain or host name, unlike an A record which points a domain name to an IP address. PTR records are used for the reverse DNS lookup.
It's A record.
No its PTR record. A record is used to map a FQDN to IPv4 address
Should be B. PTR A record maps FQDN to IP PTR record maps IP to FQDN
answer is D
Correct Answer is: D https://blog.dnsimple.com/2015/04/common-dns-records/ The A record is one of the most commonly used record types in any DNS system. An A record is actually an address record, which means it maps a fully qualified domain name (FQDN) to an IP address. For example, an A record is used to point a domain name, such as "google.com", to the IP address of Google's hosting server, "74.125.224.147".
I made an account just to reply to you. The answer is not D. The correct answer is B CNAME record is for name to name. Also known as alias record. A Record is used to map FQDN to IPv4 address AAAA Record is used to map FQDN to IPv6 address PTR Record is used to map IP address to FQDN (the opposite of an A record) Not sure if you guys arent reading the question correctly or what, but the 100% correct answer is B. The practice test is wrong.
The answer is PTR. Read the way the question is worded and you will understand why it’s not A.
A Record - Maps FQDN to IPv4 AAAA Record - Maps FQDN to IPv6 CNAME Record - Maps name to name, sometimes call alias PTR - Maps IP to FQDN (the opposite of A and AAAA)
PTR is the correct answer
A record.
it is A record
record A is to map host name to address
D. A Record
o correto é A: Este é um tipo básico que estabelece a correspondência entre um nome canônico e um endereço IP. Além disso, podem existir vários registros A relacionados com diversas máquinas da rede (servidores).
sorry it is b
Even if it were A record, why should it be AAAA (IPv6)rather than A(IPv4)? The right answer should be B
The right answer is D
This should be PTR.
I said earlier on that the correct answer is D. The A record is one of the most commonly used record types in any DNS system. An A record is actually an address record, which means it maps a fully qualified domain name (FQDN) to an IP address. For example, an A record is used to point a domain name, such as "google.com", to the IP address of Google's hosting server, "74.125.224.147".

A resposta correta seria B, o tipo de registro PTR que resolve IP para um FQDN.

That isnt the question though. The question was IP to FQDN.... not FQDN to IP
A record
No its PTR record. A record is used to map a FQDN to IPv4 address
