Using Free Public DNS

When we should use free public DNS ? Sometimes, we can't enter some websites although we can enter some websites. That may be because of DNS error of your ISP if the website is not down and your network administrator does not set any rule to block the websites. At that time, we should use free public DNS. The followings are some of free public DNS:


1. Google                                      8.8.8.8, 8.8.4.4

 

2. Norton ConnectSafe                  199.85.126.10, 199.85.127.10

VPN is used to get secured network connection through Internet. The big companies also use VPN to get secured network connection in connecting offices, industries, etc., from different locations through the Internet. (for example, most of the banks use VPN).

Generally, there are two types of VPN.(More than two if detailed)

1. Side-to-Side VPN.

2. Remote Access VPN.

Should we check mails in Spam of public emails such as Google and Yahoo?

Yes, off course. We should check the emails in Spam. Why? When the private email users send mail to the free or public email users such as Google and Yahoo, the unknown emails will be stored in Spam / Junk (that is security policy of public emails). At that time, open the email and click "Report not spam". After doing that, the emails from a private email user you've reported as "Not Spam" will be stored in Inbox. But checking the emails in Spam is the good habit for the public email users. I write this post because some public email users such as Google and Yahoo are missing the important mails from the private email users.

Thank you.

Why should we use business or private emails in business?

There are many public email providers such as google, yahoo, and outlook. We can use those public emails by free of charge. But using public emails is not as secured as private emails. Why? Millions of users are using public emails by free of charge. So, each user can't be administrated on the server. By using private emails, you will get the following benefits:

 
1. Security
We can also filter the spam mails in Public Emails. But not 100%. We can filter the spam mails in the server by using private emails. And, we can also use private encryption. So, more secured.


2. Email Names
We can't choose the email names what we want by using public email services. For example, we can't get [email protected] or [email protected]. By using private emails, you can get the email names what you want. For example, [email protected] or [email protected].


3. Impression of Customers
Using public emails is not suitable in the businesses. Using private emails is the best habit to get impression of the customers.

 
How can we get private / business Emails?

1. Google provides Google Suite for private email service.

2. Microsoft provides Office 365 for private email service and applications.

3. Setting up private / own exchange servers. It is not suitable for small business as the cost is high.

4. The best and cheapest way is using Web Mail that is included POP3, IMAP and SMTP .
