SRV, short for Service Records, connect your domain to specific services such as VoIP, instant messaging, and other such services which require networking protocols when in a hosting environment.


Important: For your records to work, your Name Servers should be set to one of the following two options, which determine where you should add the DNS Records:

  • ns3.epik.com/ns4.epik.com – DNS is managed on Epik.com Dashboard
  • host11.epik.com/host12.epik.com – DNS is managed on cPanel

The numbers may vary on the hosting name servers depending on your hosting plan. This information is emailed to you when you first purchase a plan.

If you have a third-party name servers, the DNS Records should be added on that provider’s end.


Characteristics of the SRV Records

The SRV Records have five fields that are unique to them, which all work together to connect to various services:

Service (Hostname)

The service hostname should be a descriptive or symbolic name relating to the purpose of the record. It must start with an underscore “_” – e.g. _phone (for VoIP).

Protocol

SRV Records support three major networking Internet Protocols.

  • TCP (Transmission Control Protocol) – Enables connections between applications running on hosts communicating via IP networks, establishing a connection between server and client before sending any data. Slower, but it can handle re-transmission of lost data.
  • UDP (User Datagram Protocol) – Connectionless protocol that enables the transfer of information using messages (datagrams) with substancial speed and efficiency, but allowing for the loss of data without recovery.
  • TLS (Transport Layer Security) – Cryptographic protocol that provides end-to-end security in the exchange of information between applications over the internet.

Priority

Priority in SRV Records determines which record, (with different services), is looked up first.

Weight

In the event there are two records with the same service, weight defines which one is looked up first.

Port

The Port defines which protocol port is listening for connections in the application network. It’s the communication endpoint that identifies the specific process or service to be used and where the data should be sent through.
