DNS

Introduction​

DNS (Domain Name System) is a very significant part of the internet. DNS associates a Domain Name with an IP address. For example, if you have purchased a domain name, say www.abcdef.com, this domain name requires an IP address to be processed on the Internet because everyone accesses information online through domain names. Web browsers interact through Internet Protocol (IP) addresses. DNS translates domain names to IP addresses so browsers can load Internet resources. This way, DNS servers eliminate the need for humans to memorize IP addresses.

DNS must be configured with perfect precision, and any inaccuracy in setting up the DNS record may lead to inefficient website performance. The following are the prerequisites required to configure a DNS record on your MyAccount:

  1. A Domain Name
  2. An IP address

Setup DNS Records​

Follow the steps below to configure your DNS records via the E2E Networks DNS server database.

  • Log in to the MyAccount portal using the credentials set up at the time of creating and activating your E2E Networks MyAccount.
  • On the left side of the MyAccount dashboard, click on the DNS sub-menu available under the Services section.

DNS Menu

  • You will be routed to the Manage DNS page. Now, click on the Add Domain button to create a DNS recorded.

Add Domain

Enter the Domain Details​

Every domain requires an SOA record (Start Of Authority Record) configuration when transitioning from its parent domain. For instance, if abcdef.com is your domain name and you want to point it to E2E Networks DNS servers, the SOA records for abcdef.com must be configured in our DNS portal. Fill in the required parameters as follows:

SOA Record Form

  1. Domain Name: Enter the exact domain name you own or have bought.
  2. IPv4 Address (External IP): Enter the public IP address under the IP address section.

Note: The domain name should not have "www" at the beginning.


After filling in all the details, click the Submit button.

Submit Domain

Change Nameservers for My Domains​

Nameservers are your primary DNS controllers. Without the correct nameserver settings, your email and website won't work correctly. You need to change your nameservers to those provided by E2E Networks.

  • Name Server: All the information related to your domain name will be stored and maintained by the Name Server.
  • Link the E2E Networks nameserver provided in your domain service provider portal.

Nameserver Example

Create Your Domain Records​

Once the SOA records are saved, your domain will be created in the E2E Networks DNS database. To configure DNS records for your domain name:

  • Click on the Manage action next to your domain name and IP address.

Manage Domain

  • You will be directed to the Edit DNS Record page, where a summary of your domain name will be displayed.

Edit DNS Record

  • Click the Add Record button to add various DNS records to the zone file.

A Record (IPv4)​

An A record directs a visitor's browser requests to an origin web server. Multiple A records can be added with different IP addresses for the same subdomain, allowing DNS to alternate requests among them. Follow the steps below to create an A-Type Record:

A Record Form

  • Select A record type from the dropdown list.
  • Enter the Hostname in the hostname field.
  • Enter TTL (Seconds): The recommended TTL for A records is 14400 seconds, meaning changes take up to 240 minutes (14400 seconds) to take effect.
  • Enter the IP address to which the domain name should resolve.
  • Click the Submit button.

Notes:

  • A generic hostname field ending with a . (dot), such as abcdef.com., is considered a Fully Qualified Domain Name.
  • A blank hostname field or one with an @ symbol is treated as the base domain (abcdef.com).
  • A hostname without a trailing . (dot) will be treated as abcdeff.com.abcdeff.com.abcdefff.com.

AAAA Record (IPv6)​

An AAAA record points a domain name to an IPv6 address. If your domain has an IPv6 address, use an AAAA record. You can add multiple AAAA records for the same subdomain with different IPv6 addresses.

AAAA Record Form

  • Select AAAA record type from the dropdown list.
  • Enter the Hostname in the hostname field.
  • Enter TTL (Seconds): The recommended TTL for AAAA records is 14400 seconds (240 minutes).
  • Enter the IPv6 address to which the domain name should resolve.
  • Click the Submit button.

CNAME Record​

The CNAME record is utilized when a domain’s alias name is to be created. CNAME Records are necessary to direct a visitor's browser requests to an origin web server. Unlike an A record, the CNAME will point to a hostname like www.example.com instead of an IP address. www.example.com would then either have an A record that lists the IP address or use another CNAME record that points to a different hostname. Eventually, a chain of CNAME records must point to a hostname that resolves to an IP address.

For example, an alias name of docs.abcdef.com can be documents.abcdef.com using the CNAME record.

CNAME Record

  • Select CNAME record type from the dropdown list.
  • Enter Hostname in the hostname field.
  • Enter TTL (Seconds). The recommended TTL for CNAME records is 32600 seconds. This means that if an A record gets updated, it takes 543 minutes (32600 seconds) to take effect.
  • Enter the domain in the Point To field.
  • Click on the Submit button.

MX Record​

MX record (Mail Exchange Record) is related to the Mail Servers present in your Domain’s server. It’s responsible for the reception of the emails based on their respective mail servers.

MX Record

A DNS 'mail exchange' (MX) record directs email to a mail server. The MX record indicates how email messages should be routed in accordance with the Simple Mail Transfer Protocol (SMTP, the standard protocol for all email). Like CNAME records, an MX record must always point to another domain.

TXT Record​

The TXT Domain Record provides information regarding your server, datacenter, or a network in a user-readable format. For instance, you can verify the ownership of a domain using the TXT resource record. You can create SPF, DK, DKIM text records.

TXT Record

For example, enter v=spf1 mx -all (to make sure that all emails are sent from this server and no other servers are authorized).

  • Select TXT record type from the dropdown list.
  • Enter your hostname (e.g., mail.abcdef.com).
  • Enter TTL (Seconds). The recommended TTL for A records is 14400 seconds. This means that if an A record gets updated, it takes 240 minutes (14400 seconds) to take effect.
  • Enter the rule in the Text area.
  • Click on the Submit button.

SRV Record​

SRV records specify the location (hostname and port number) of servers for specific services. You can use service records to direct certain types of traffic to servers.

SRV Record

  • Select SRV record type from the dropdown list.
  • Enter your service name.
  • Enter Target value.
  • Enter the Priority value.
  • Enter the weight value.
  • Enter the port.
  • Click on the Submit button.

Final Output​

Once you have successfully configured the above-mentioned Record Types for your domain, you will have a final output summary. You can review and edit all the existing records.

Final Output

Domain Records are the basic information elements of the domain name system. Each record has a type (name and number), an expiration time (time to live), a class (record type), and type-specific data (value).

Note: Please refresh the page in case you fail to see the Domain summary.


Diagnostics​

Once you have filled all the required fields and updated the Nameserver information record, your domain name should be up and supported in a few hours. Go to the Diagnostics section to get a report of your domain. Click the refresh button in case the details are not updated.

Diagnostics

You can confirm your hostname registration with E2E Networks. Open command prompt/shell and run the ‘ping’ command: – Check the server IP Address and the response.

ping www.abcdefff.com
64 bytes from 101.53.131.214: icmp_req=1 ttl=60 time=1.05 ms  
64 bytes from 101.53.131.214: icmp_req=2 ttl=60 time=0.450 ms

Custom Reverse DNS​

Reverse DNS lookup is a DNS query for the domain name associated with a given IP address. This accomplishes the opposite of the more commonly used forward DNS lookup, in which the DNS system is queried to return an IP address.

How does reverse DNS work?​

Reverse DNS lookups query DNS servers for a PTR (pointer) record; if the server does not have a PTR record, it cannot resolve a reverse lookup. PTR records store IP addresses with their segments reversed, and they append ‘.in-addr.arpa’ to that. For example, if a domain has an IP address of 10.0.0.1, the PTR record will store the domain's information under 1.0.0.10.in-addr.arpa.

Pre-requisites​

  • A Custom reverse DNS record can only be set for an IP belonging to E2E Networks.
  • Nameserver information record of the domain should point to E2E DNS nameservers.
  • An A record should exist for the target.

Setup Reverse DNS​

Follow the steps mentioned to configure your reverse DNS records via the E2E Networks DNS server database.

  • Go to the Manage DNS page. You have to click on the ‘Add Reverse DNS’ button to create a reverse DNS record.

Add Reverse DNS

You will be redirected to the “Manage Reverse DNS” page. You have to click on the ‘Add Record’ button to create a reverse DNS record.

Manage Reverse DNS

Enter the following information:

Enter Reverse DNS Information

IPv4 Address (E2E Network IP): Select the ‘public IP’ address from the dropdown list under the IP address section.
Domain Name: Enter the exact domain name that you own or have bought.


Note: The domain name should not have a "www" at the beginning.
