Setting up DNS RecordsThis group of tutorials shows you how to add a certain type of DNS Record in the control panel.
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.
AFSDB: AFSDB records are used for locating AFS and OSF type database resources through the DNS.
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
182.112.33.47.
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.
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 example.com will also apply to any subdomain, such as sub.example.com unless it is overridden.
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 alias1.yourdomain.com to a different record such as yourdomain.com. alias1.yourdomain.com will then
clone all records for yourdomain.com and alias1.yourdomain.com will go to the same location as yourdomain.com.
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.
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.
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.
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.
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.
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).
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( yourodomain.com ) 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:
- NS1.DYNU.COM
- NS2.DYNU.COM
- NS3.DYNU.COM
- NS4.DYNU.COM
- NS5.DYNU.COM
