The internet is constantly changing. There has been a constant rise in the number of users along with a surge in providers of online services. In response, the scale of the internet has also increased, but this has led to it become even more complex and volatile. Today, DNS is a very influential and powerful tool. It empowers information technology leaders to have better control over the IT infrastructure.
Ensuring that your company has a correct DNS map that is a readable name to IP addresses and helps people to reach their online service destination is usually a website or an application. The same can be accessed through a Uniform Resource Locator, also known as URL. For example, the domain www.Google.com translates to IP address 8.8.8.8.
There are many individuals and companies who are managed DNS providers as well as experts in the field. The term DNS is quite commonly used, and many non-IT professionals are also aware of this term. However, there are a few other terminologies that are quite prevalent in the DNS glossary which can cause confusion among some IT professionals if not understood correctly.
Here are a few of those terminologies that IT departments may want to know but might be afraid to ask:
AAAA Records – This indicates a hostname that is pointed to an IPv6 address.
Active Failover – This allows your online services to be active and run continuously without disruption. It also delivers a seamless experience to visitors. In lieu of an outage, the traffic is re-routed to another pre-configured endpoint.
Auth Code – This is also known as an EPP code or a transfer code. It is a string of 8 to 16 characters in length and is created on a random basis at the time of domain registration.
Border Gateway Protocol – This is the routing between multiple domains by finding the best path.
Data Center – The data center is the place where servers, computer systems, and other telecom components are hosted.
DDNS (Dynamic DNS) – Typically, a DDNS is used by home users who want to send out dynamic IP address updates to a static hostname.
A Record – A record indicates a hostname that is pointed to an IPv4 address.
The list of DNS terms is endless, but these are just a few of which any IT professionals should be aware. It is better to obtain a complete list of such terminologies from your Managed DNS provider along with definitions to ensure you are speaking the same language.
