DNS Management

Rama Sadhu Updated by Rama Sadhu

Introduction

Domain Name System (DNS) is a database where domain names are located and translated into Internet Protocol (IP) addresses. Apptrana DNS management enables users to maintain all the DNS records and hosted zones. Also, AppTrana DNSSEC protocols help in mitigating potential security issues. 

Go to Groups & Assets > DNS Management. 

DNS management is mainly divided into two sections, that is Hosted Zones and DNS Records. 

Hosted Zone

All the list of hosted zones added are displayed in this section. Customers can also add a new hosted zone or delete the hosted zone. 

When a hosted zone is added, by default SOA and NS records are added. 

Create Hosted Zone 
  • Click Add New. 
  • Enter the hosted zone name. 
  • Add description in the respective field. 
  • Select the promocode. 
  • Click Save. 
Delete Hosted Zone

Click Delete to remove hosted zone. A confirmation pop-up appears. 

Supported DNS Record Types

A DNS record is used to translate domain names to IP addresses, route email to mail servers, identify name servers responsible for a particular domain, and provides additional information about a domain. 

In AppTrana we support the following types of DNS Records. 

Record Type 

Description 

A (IP version 4)) 

A record maps a domain to IPv4 address. 

AAAA (IP version 6) 

AAAA record maps a domain to IPv6 address. 

CNAME (Canonical Name Record) 

CNAME maps an alias or subdomain to main domain. 

MX (Mail Exchanger Record)  

MX record directs email to mail server. 

TXT (Text Record) 

TXT records hold arbitrary text information. 

NS (Name Server Record) 

Delegates DNS resolution to another nameserver. 

SOA (Start of Authority) 

Specifies DNS zone information. 

SRV (Service record) 

Specifies the location of a service like instant messaging, VoIP (Voice over Internet Protocol). 

Name Servers

Name servers allow web browsers and other online resources to access websites. This field shows the list of name servers. 

Go to the name servers' field and copy the 4 servers listed. 

 Examples:  

ns-1654.awsdns-14.co.uk,  

ns-680.awsdns-21.net,  

ns-355.awsdns-44.com,  

ns-1174.awsdns-18.org

Record Value 

A record value is information associated with a specific DNS record type. 

Example:  

A Record, value: 192.0.2.146, 192.168.1.1  

AAAA Record, value: 2001:0db8:85a3:0000:0000:8a2e:0370:7334 

CNAME Record, value: www.example.com to example.com 

MX- 

TXT Record, value: Text string 

SRV Record, value: _sip._tcp.example.com 

Record Name 

 Enter the record name followed by domain address. 

TTL 

Enter Time To Live (in seconds) to specify how long the information is guaranteed to be valid. (Record caching duration) 

  • Click Save. 
Manage/Delete DNS Record  

Click on the Edit button.

Manage DNS Record page appears. 

Customers can modify the record information provided. Once the information is modified, click Save. 

If the record is no longer required, click Delete. A confirmation pop-up appears. Approve the confirmation to delete the DNS record.
