Types of DNS zone records
DNS is like a directory, tells your visitors to go to where to fetch a particular service. For example, email is location A and website is location B.
That’s mean to say, it is not necessary to host your website and email servers at the same place as well as your subdomain. Actually, I have spoken to many, they have the perception the services must be located on the same server which is not true.
DNS and its zone records are also neglected by most. Many think I will only need a domain name and a web hosting. This is wrong, but usually, DNS is provided at no cost when you registered a domain but you will till need them.
Today, we will walk you through the common DNS zone records we are using with a domain name.
- A record – this is to resolve a name to an IPv4 address. For example, the IP address of your server or website.
- CNAME record – is an alias name to another domain.
- MX records & Priority – They are your serves to receive emails on your domain behalf. Priority 10, 20 & 30 if you have more than one MX and where should the emails deliver based on its priority.
- TXT – The field used as information. Like SPF, DKIM, DMARC and some may have it for validation.
- AAAA record – Work like A record but for IPv6 addresses.
There are other not so common records like NS probably already added by our DNS provider or SRV used by certain service provider. Hope the above information is useful.
Related to a Domain
Today, we talk about a domain name. This article is based on my past experience on a few TLD types of domains, like the .com, .com.sg, .sg etc. Hopefully, it helps some in a way if this information is useful.
- If you are registering a .sg domain, it is in the month of August or you can wait till August. It will save you money. SGNIC runs a promotion on the price reduction of .sg domains in that month to celebrate Singapore National Day.
- Check out our domain page, there are always TLDs on promotion, it could be the one you wanted to register.
- Plular or singular of a domain name, to avoid any mistakes and if your budget allowed, register both. For example, cat.com and cats.com use one as an alias to your preferred domain.
- A domain name is too long is difficult to remember, you should avoid.
- Using a ‘dash-, for example, cat-house.com and cathouse.com, register both and use one as an alias to your preferred domain.
- Domain should be easy to remember, ask a few people and get feedback.
- A domain name represents a person, a brand or a thing. If they are not related, it is difficult to recall.
- Never let your domain expired. Sg domain, you can renew up to 2 years and other TLDs may be renewed as long as 10 years. A redemption fee may apply if your domain has expired.
- Avoid domain ID protection especially for anyone are doing business online. ID protection might indirectly or directly affect your creditability.

Today, we talk about a domain name. Guess I do not need to explain what is a domain name but many do not really understand what is the function of a domain name. In the 1st place, a domain name is not web hosting. A domain name is a name where you have registered with the authorized registrar or their reseller. A domain name is portable, it doesn’t matter where you have stored your data, email and web content. Similarly, it is like the Television license that you have to pay yearly to maintain its validity.
Each domain has the assigned DNS this is the element to tell people where you are hosting your email and website. But you will definitely need a domain name so you can tell people what is your email address unless you are not hosting but use the free email services from Gmail, Yahoo, Hotmail etc.
We usually register a domain name related to a person or a business. Some maybe their interest or service. Anyway, this isn’t my point. My point is how to choose a correct domain name. Here are a few tips to make a better choice on registering a domain name.
- Name after you or your business. So, you remembered the domain name as you remembered to the person or his business.
- Easy to remembered. I will forget if the domain name is mot common name.
- Keep it short not too long. Difficult to remembered and easy to have a typo.
- Check its availability and made a few choices before you are registering,
- Registering a domain name related to your product or service that you are providing.
- Register a territory TLD of a domain name. Example, my business is in Singapore, I can choose to register a domain name ends with .sg or .com.sg but not .my or .com.my
A domain name is unique. As long as it is registered, you can’t register again. However, there are services or you can approach the registrant, make an offer to buy from them. if the amount is agreed by both parties, you can make a domain transfer to gain ownership.
Like what is explained in DKIM.org, DomainKeys Identified Mail (DKIM) enables an organization to take responsibility for an email sent. The organization is a handler of the message, either as its originator or as an intermediary. Their reputation is the basis for evaluating whether to trust the message for further handlings, such as delivery. Technically DKIM provides a method for validating a domain name identity that is associated with a message through cryptographic authentication.
DKIM works only from the originator email server. Most modern email servers allow you to enable and sign each outgoing email. The administrator is responsible to add the DKIM key as a text file into the domain DNS record. If the DKIM keys match, the email is genuinely sent from the originator’s email server. This helps to fight spam emails and enhanced email delivery. But wait a minute…
Provided the recipients’ email servers are checking on DKIM. Yes, google email gateways do but I have seen many others don’t. So, my question is if you do not enable DKIM, does it mean you cannot send outgoing emails. The answer is ‘NO’. Apparently, even you do not have DKIM you can still send to Gmail users or any recipients email servers checking n DKIM. So, the purpose of DKIM only enhances its delivery if your recipient email servers are checking on DKIM. But this is how I look at, DKIM is good to enable if users are told to send their emails via a designated email server but definitely not a must at least for now.
Most have the idea that more expensive web hosting is better we bosting. Actually, it is not true. A shared web hosting might be good or enough for some users. If their website is hosted on a dedicated server, paying much more but they will unlikely see the difference. We call it overkill.
Most personal or small business website can use shared hosting. With Sucuri Web Application Firewall, you can still enjoy close to enterprise website protection. Plus the affordable monitoring from Sucuri, your shared hosting website is top notch in my perspective.
If you have met the following criteria, you can consider hosting your website on a shared hosting.
- Got a very low budget < $100 per year.
- Only a WordPress website or something similar.
- I just want to introduce my business online.
- I want to create 5 or fewer email accounts.
- I update my website once a month the most.
- Sharing IP is alright as long they come to my website using my domain name.
- Only a few visitors each day, and do not have any online transaction.
If you have met most of it, you are safe to subscribe to a shared hosting.
If you are registering a .com.sg, you need a registered business or company in Singapore. An admin has issued with Singapore identity card, typically a Singaporean or a permanent resident of Singapore.
Foe .sg domain registration, the registrant must have a valid Singapore card identity and both the registrant and admin can be the same person. Both types of domain registration require the admin to verify the newly registered domain using their SingPass at VerifiedID website.
