Zorluk: KolayIP Addressing Services

A network administrator needs to configure a DNS resource record to resolve a web server's domain name directly to its 32-bit IPv4 address. Which of the following DNS record types should the administrator create?

  1. An A recordCevap
  2. B
    An AAAA record
  3. C
    A CNAME record

An A record is used to map a hostname or domain name to an IPv4 address.
An Address (A) record maps a fully qualified domain name (FQDN) directly to a 32-bit IPv4 address, fulfilling the host name resolution requirement.

Adım Adım Çözüm

1
Identify the target service and requirement
The requirement is to map a domain name directly to a 32-bit IPv4 address within DNS.
DNS resolution requires selecting the specific record type corresponding to the target data type (IPv4 vs IPv6 vs Alias).
2
Evaluate standard DNS record types
An Address (A) record is specifically designed for 32-bit IPv4 host address mapping.
Different DNS record types serve distinct functions; A records handle standard IPv4 forward lookups.
