Email forwarding: Why should you use it?

Email forwarding is a very useful tool for your business. This is a quick and straightforward method to automatically redirect all emails that are going to a particular mailbox. What is the process behind it, and how useful it may be we will see in today’s article.

What is email forwarding, and how does it work?

Many DNS providers offer email forwarding, which allows you to transfer traffic from one email address to another at the domain level (without the need for a particular software). Furthermore, it differs from an email user who forwards a message to another person or the email forwarding feature of Gmail and Outlook. If you are the domain name administrator, you can redirect incoming emails from one of the domain name’s email addresses to an individual email address. For example, you can forward any email to your Gmail, Hotmail, or other email address (emailname@gmail.com) using your personal mail address (emailname@domain.net).

What are the benefits of using it?

There are many advantages to using this method, one of them are as follows:

  1. Merge email traffic from several inboxes into a single inbox. That way, you’ll have all of your emails in one location and be able to manage things more easily. It could be helpful if you have many businesses and want to access all of your emails in one place.
  2. There is no software associated with email forwarding. As a result, you can use the software you want without any issues. The email forwarding will continue to function.
  3. Redirect traffic from an email address on your domain that you don’t own to the one you do. Consider the following scenario: an employee has left the firm, but others are still attempting to contact them via email, and you don’t know the password. You can now divert traffic and get it in a different inbox.
  4. It’s beneficial if you want an email account with a public domain. Rather than using a shared email provider like Google’s Gmail, most business people use email accounts with their domain names. The goal is to project a professional image and earn their clients’ trust. 

The difference between email forwarding addresses and regular email addresses

Because they are different services, their addresses are also separate.

  • A traditional or regular email address has its own inbox, which you may use to send, receive, and read your messages. You can open your inbox through the web or with an email provider (like Gmail).
  • Incoming messages are directly transferred to another email when you use a forwarding email address. So, you can access your email through the inbox of the other account.

To summarize, regular email provides a well-known inbox for sending, receiving, and other types of messages. So, the email forwarding does not work in this manner, nor does it save messages. Instead, it will automatically forward all mails from one address to another that you specify. Therefore, it is not possible to use the same email address for both services at the same time.

What is the best place to get email forwarding?

The majority of the time, the email forwarding is a paid service. Domain name hosting providers offer this service. That is, you should look into DNS service companies to see if they offer this feature. Often it’s part of their paid plans, and there are set quotas, but in rare cases, you can find limited email forwarding on free DNS plans.

Conclusion

We can infer that еmail forwarding is a very cost-effective alternative for your company’s success! In several cases, it is definitely an advantage to avoid losing contacts that mean money for your business. So why not give it a shot? Consider it the next step in your company’s strategy.

DNS cache – What is it?

DNS cache – Definition

The DNS cache represents a cache memory for storing DNS data (DNS records) for particular domain names only for a short amount of time. This type of memory mechanism could be found in various devices, machines, smartphones, computers, DNS recursive servers, and more.

There is one main purpose which DNS cache aims at, that is simply not to repeat the long and time-consuming DNS lookup each type a precise domain name is requested.

For instance, you type domain.net in your address bar, and a DNS lookup is triggered by your request to search for its IP address. Then the DNS recursive server finds the needed IP address, and you are able to explore domain.net. All of the DNS records are going to be stored in the DNS cache. So, next time you want to visit domain.net, it is going to load a lot faster because the needed data is going to be in the DNS cache. 

We should mention that the IP address and the DNS data are going to be available in the DNS cache only for a particular amount of time. That amount depends on the TTL (time-to-live) value which is set by the DNS administrator.

Thanks to this caching mechanism, users receive faster answers to their DNS queries which also helps with optimizing the overall resources.

How to clear your DNS cache? 

If you want to clear the DNS cache, you could do it in one of several ways. Here is how to complete this task depending on your browser and your operating system (OS). 

macOS

If you are a macOS user, you should start by opening the Terminal app. Then you just need to type the following command:

sudo killall -HUP mDNSResponder

After that, you should type your password and press Enter. That’s it!

Linux (Ubuntu 20.04 LTS)

In case you are a Linux user, then you also should open the Terminal app. Next, type the following command:  

sudo systemd-resolve –flush-caches

After that, you should type your sudo password and press Enter. That’s it!

Windows

If you are a Windows user, then you should open the Command Prompt or Windows PowerShell. After that, type the following command:

ipconfig /flushdns

Lastly, you should see a confirmation message. That’s it!

Google Chrome/Edge/Opera

Inside your address bar, copy and paste the following line:

chrome://net-internals/#dns

Press Enter, and on the page, you should search for “Host resolver cache” and click on “Clear host cache.”

You are ready!

Safari 

Go to “Preferences” and then click on “Advanced.” Then, search for “Show develop menu” in the menu bar.

After that, search for “Develop” and then click on “Empty Caches.”

The last step is to restart your browser. 

Ready! 

Why should you care?

Based on the fact that DNS cache is really helpful, cybercriminals managed to find a way and take advantage of it. They perform an attack called DNS poisoning (DNS spoofing) and insert fake data (IP addresses and domain names). Such type of fraudulent DNS data (DNS records) directs users to a website that is similar to the original one, yet it is under the control of the criminal. Therefore, it is important to know that flushing the DNS cache regularly could prevent such malicious threats. 

Why should you implement Dynamic DNS?

Many of you came to this article because you want to make available a particular service from your home or office on the Internet. Dynamic DNS will serve you this purpose! It is easy to implement, and it will save you money, and it could even be free if you don’t require a lot of resources. Do you want to learn more? 

What is Dynamic DNS?

Dynamic DNS (DDNS) is a DNS service that allows you to create a hostname for a device and link it to its IP address. It is a simple A or AAAA record so far. The Dynamic part comes from the fact that you can set up your router to report changes in this device’s IP address and send an update message to the DNS server where the link was made. There the hostname’s IP address will be updated. It is a way to automatically update the IP address of a device and provide availability with the need of human effort. You can set up the Dynamic DNS and be sure that the service you are running will be available. 

If you are not using this DNS service and want to use a device to provide a service, you could have the following problem. The Internet Service Provider (ISP) that you are using will eventually update your IP address using a dynamic method like DHCP. As a result, you will get a new IP address, and all the clients need to get it to reconnect. Unfortunately, if you are not near the device, you might not know the new IP address and experience long downtime. 

You can also pay for a static IP address and provide service from your device without worrying that the IP address will change. In this case, there are two problems. First, it cost more than a Dynamic DNS. Second, if your IP address is always the same, hackers could easily target your device. They will know it and try everything to exploit it in different ways. Not a good scenario. What do you think?

Why should you implement Dynamic DNS?

The main reason is very simple – Dynamic DNS is the cheaper option to make something available online. Yes, you can get static IP addresses for each of the connected devices that you want available, but how much will this cost? The IPv4 addresses are getting very scarce and quite expensive. So, if you are wondering, even if you pay for a DNS service plan, it will still be a lot cheaper than paying for static IP addresses. 

The second important point is that it is relatively easy to use. Setting up Dynamic DNS is like setting anything on your router. You go to the setting and input what is needed. On the other side – the DNS, it is also very quick and straightforward to create an account on a DNS site, and later, create a new host. 

So, basically, Dynamic DNS is an economical and easy-to-use alternative to the paid static IP addresses. 

Conclusion

You have just learned what is Dynamic DNS and what are its most important advantages, compared to static IP addresses for your host. Should you use it? In most cases, using it will save you money and will work fine, so definitely consider it. The only concern is that the Dynamic DNS is only good as the DNS provider. If you can’t afford downtime, think well, which DNS provider you should choose.
