Create Key record
Dynu gives you full control over all the DNS configurations for your domain names.
You can log onto the control panel to manage your DNS records.
SRV record allows multiple servers providing a similar TCP/IP-based service to be located using a single DNS query operation. This record enables you to maintain a list of servers for a well-known server port and transport protocol type ordered by preference for a DNS domain name. The naming system of SRV record is an underscore followed by the name of the service, followed by a period, and underscore, and then the protocol, another period, and then the name of the domain. For example, _http._tcp.yourdomain.com would be the service record for web requests for yourdomain.com.
To add an SRV record in the control panel, you may follow these 3 steps.
Step 2
Go to
DNS Records
to add an SRV Record.
Node Name Enter the subdomain name, for example, subdomain1. Leave empty for primary domain name.
Type Choose "SRV-Service".
TTL How long the server should cache the information.
Hostname Also called "target". It specifies the DNS domain name of the host that provides the type of service being requested.
Priority Sets the preference for a host specified in the Hostname field. The lower the number, the higher the priority. The range of preference values is 0 to 65535.
Weight Used in addition to Priority to provide a load-balancing system where multiple servers are specified in Hostname field and are all set to the same level of preference. It is a relative weight for records with the same priority, a higher value means more preferred. If load balancing is not needed, use a value of 0.
Service The symbolic name of the desired service. For example, telnet, http or smtp.
Protocol The transport protocol of the desired service. It is usually either TCP or UDP.
Port The server port on the target host that provides the service. For example, 80 for http.
Step 3
Check if your SPF record has gone into effect using DNS Lookup tool. Enter _smtp._tcp.dynu.biz as Hostname, and choose "SRV-Service" as Type.
