Introduction

Atlantic.Net’s Cloud Servers Administration Interface includes a DNS management module that enables you to manage DNS records for your domains. This tutorial will show you how to manage these settings in the cloud.atlantic.net portal.

Procedure

Once logged into the Cloud Servers Administration Interface, click “DNS” on the left side of the page.

Select DNS to view your servers

Your Servers

Adding a domain

On the initial Manage DNS page, you’ll see a list of domains you’ve added to the system and a link “Add Domain” used to add a domain.

Select Add domain

Domain Names

Click “Add Domain” and a dialog will pop-up prompting you to enter the domain name you wish to add.

Enter the domain name you wish to add

Enter the domain name you wish to add

Enter only the domain name. i.e. If your server is going to be www.example.com, and you own the example.com domain, you would enter example.com here. Entering a domain into the DNS Manager does not register the domain. You will need to register the domain or already have registered the domain, and set its name servers to:

ns1.quickroutedns.com
ns2.quickroutedns.com
ns3.quickroutedns.com

After you add a domain to the DNS Manager, you will get a popup that says “Domain created successfully” like the picture below.

After hitting “OK” on the popup you will go back to the initial DNS Manager page with a list of your domains, and links next to each one called “manage” and “delete”. Delete will delete the domain and all associated DNS records from the system. Manage will take you to the management page for that domain.

DNS record management

There are seven different records types (A/AAAA, MX, CNAME, TXT, PTR, SRV and NS)  that are suppored. To add records you will need to click manage on the domain name you want to make changes to.

Click Manage on the domain you would like to add records to.

Click Manage on the domain you would like to add records to. In the mange DNS screen you are able to add your DNS type add your host and your content.

Add the record type of your choice

Add the record type of your choice

The following recods can be added.

A/AAAA Host Records

The Host Name (A or AAAA) records are used to map DNS names to IPv4 and IPv6 addresses. i.e. If you wanted to setup www.example.com to resolve to a server with IP address 192.0.2.2, you would need to create an A record in the example.com domain by placing www in the ‘Host’ field and the IP address192.0.2.2 in the ‘Content’ field.

Alias / CNAME Records

The Alias Name (CNAME) records are a form of aliasing in DNS. If you want a server to have multiple names, but only want to change one record if the IP address changes, CNAMEs are a good choice. i.e. You have www.example.com pointing to 192.0.2.2. You want this system to also have the name stats.example.com, enterstats for the ‘Host’ field, and www in the ‘Content’ field. A record name that is a CNAME cannot have any other record types. i.e. Once you’ve added the CNAME pointing stats to www, you cannot create a stats A record, TXT record, etc.

 

Mail Exchange / MX Records

The Mail Exchange (MX) records are used by mail servers to determine which servers should be used for delivery of email. MX records point to host names that themselves have A or AAAA records and have a priority. The priority of the MX record determines the order in which it is used with smaller numbers being preferred. In most simple cases, you’ll have a single MX for a given name. You can leave the ‘Host’ field blank. If you want the MX for example.com to point to example.com, enter example.com in the ‘Content’ field. If you want the MX to point to www.example.com, you can just enter www in the ‘Content’ field.

 

 

TXT Records

 

The Text (TXT) record is used to store arbitrary text. They can be used to store descriptive information about a host, SPF records, etc. To enter a TXT record for the domain (as you might do for SPF), leave the Host field empty and enter the TXT value in the Content field.

Service / SRV Records

The Service (SRV) record is used to specify the hostname and port numbers for servers of a specified service. As an example, You would place _sip._tls in the ‘Service Name’ field, sip.example.com in the ‘Domain’ field, 10 in the ‘Priority’ field, 100 in the ‘Weight’ field, and 5060 in the ‘Port’ field.

 

Name Server / NS Records

The Name Server (NS) record is used for maintaining the name servers for your domain. Several NS records are automatically generated indicating that the Atlantic.Net Cloud Name Servers are authoritative for your domain. Removing or altering these records (other than TTL) is not recommended. To create a new NS record or delegate a subdomain, fill in the ‘Host’ field (or leave blank if this is an NS for the domain itself), and the ‘Content’ field with a name server (which must be a hostname that has an A or AAAA record. It can not be an IP address). As an example, if you want a name server called ns.yourdomain.com that points to ns1.provider.com you would enter ns.yourdomain.com in the ‘Host’ field andns1.provider.com in the ‘Content’ field.

Reverse / in-addr.arpa DNS

To setup or edit the reverse (in-addr.arpa) DNS for your cloud server IPs, click Server PTRs on the left edge of the page.

On the Server PTRs Records page, you can create, edit, or delete PTRs for your cloud server IP addresses.

Enter or edit text in the Points To column for the IPs for which you want to add/edit/remove PTRs and click Save Changes.
