Zorluk: OrtaIPv6 Addressing and Deployment

A network administrator is configuring dual-stack services on an enterprise internal network. The administrator needs to create a DNS entry on the local domain controller so client systems can resolve the host name `app.corp.local` to its assigned IPv6 address `2001:db8:10:50::100`. Which of the following DNS record types should be created?

  1. AAAA recordCevap
  2. B
    A record
  3. C
    CNAME record
  4. D
    PTR record

Cevap

An AAAA record must be configured on the DNS server.
The quad-A (AAAA) record is specifically designed to resolve domain names to 128-bit IPv6 addresses in DNS forward lookup zones.

Adım Adım Çözüm

1
Identify the destination address family required for host name resolution.
The target address `2001:db8:10:50::100` is a 128-bit IPv6 address.
Selecting the appropriate DNS resource record type requires matching the record type with the IP version being resolved.
2
Select the corresponding forward lookup DNS record type for IPv6.
An AAAA record maps host names directly to IPv6 addresses.
Standard IPv4 host records use A records, whereas IPv6 uses AAAA (quad-A) records.
