Setting up DNS Records Setting up DNS Records

This group of tutorials shows you how to add a certain type of DNS Record in the control panel.

Dynamic DNS service A record   A: An “A” record, which stands for “address” is the most basic type of syntax used in DNS records, indicating the actual IP address of the domain.

Dynamic DNS service AFSDB record   AFSDB: AFSDB records are used for locating AFS and OSF type database resources through the DNS.

Dynamic DNS service AAAA record   AAAA: AAAA records are IPv6 address records which map a hostname to an IPv6 address. Currently, IP addresses are based on version 4 of the internet protocol, where there are 4 numbers ranging from 0-255. For example IPv6 has a much larger address space where there are 8 numbers ranging from 0000-FFFF. For example, 2001:db8:85a3:8d3:1319:8a2e:370:7348. IPv6 also has protocol enhancements for security as well as many other features.

Dynamic DNS service CAA record   CAA: The “CAA” record stands for Certification Authority Authorization and serves to specify which certificate authorities (CAs) are allowed to issue certificates for a domain. Adding a CAA record to a domain allows you to reduce the likelihood of someone obtaining an unauthorized SSL certificate for your domain. CAA records are also inherited by subdomains which means that a CAA record set for will also apply to any subdomain, such as unless it is overridden.

Dynamic DNS service CNAME record   CNAME: The “CNAME” record stands for “canonical name” and serves to make one domain an alias of another domain. CNAME is often used to associate new subdomains with an existing domain's DNS records. It allows you to point to a different record such as will then clone all records for and will go to the same location as

Dynamic DNS service HINFO record   HINFO: A HINFO-record specifies the host/server's type of CPU and operating system. This information can be used by application protocols such as FTP, which use special procedures when communicating with computers of a known CPU and operating system type.

Dynamic DNS service LOC record   LOC: A LOC record specifies geographic location information for a domain name. It contains the following information: Latitude / Longitude. Altitude. Size (diameter of the location described). Horizontal / Vertical precision of the data.

Dynamic DNS service MX record   MX: A mail exchange record (MX record) is a type of resource record in the Domain Name System that specifies a mail server responsible for accepting email messages on behalf of a recipient's domain, and a preference value used to prioritize mail delivery if multiple mail servers are available. The lower the preference number, the higher the priority. You can have many MX records for a domain, providing a way to have redundancy and ensure that email will always be delivered.

Dynamic DNS service SPF record   SPF: Sender Policy Framework (SPF) records allow domain owners to publish a list of IP addresses or subnets that are authorized to send email on their behalf. The goal is to reduce the amount of spam and fraud by making it much harder for malicious senders to disguise their identity.

Dynamic DNS service SRV record   SRV: An SRV record is an advanced type of record which allows you to specify services that you have on your domain, most commonly used with SIP configuration.

Dynamic DNS service TXT record   TXT: A TXT (text) record is used to hold some text information. You can put virtually any free text you want within a TXT record. The most common uses for TXT records are Sender Policy Framework (SPF), DomainKeys (DK), and DomainKeys Identified E-mail (DKIM).

Dynamic DNS service URI record   URI: A Uri Record is a DNS record used to represent raw actions. A URI consists of a prefix and its contents. The record is a means for publishing mappings from hostnames to URIs.

NOTE: To avail our dynamic DNS service, you must list at least one of Dynu name servers for your domain name. If you registered your domain name( ) with Dynu, Dynu name servers are already listed for your domain name. If your domain is with some other registrar, you need to change the name servers at your current registrar.

Dynu name servers are:
