Web designing companies use Domain Name System (DNS) to manage the internet traffic. The most common Domain Name Systems are address (A) record, CNAME records, name server (NS) records and mail exchange (MX) records. Web designers manage the configuration of DNS for their clients who point the Name Server Record to the new host. A web developing company uses DNS to set up domain forwarding, setting up emails, and to point name servers.
In configuring the DNS server, a number of database files are set up. Then a DNS server daemon executes a boot file. Consequently, the boot file instructs the daemon server to instruct another series of database files. This in turn instructs the server sufficient information serve names.
Address Record (A); websites use an Internet Protocol (IP) address to be identified on the internet. When setting up the client's domain name to identify the correct IP address, the web designing company uses A record to point the customer's domain. CNAME; points to A record or any other website
Name Server Record (NS); informs the internet all records held by the server. Best experienced Web designing companies do not tell their customers to change this. This is because if the Name Server is changed, all other records on the client's is invalidated thus deleting other custom records previously held.
Mail Exchange Record (MX); informs the internet where to direct the email. The client's email may be hosted at the office on an exchange server. Further, the email can be hosted on the server as a Google App or using the registrar. Internet traffic is directed by MX records to the right email servers. This enables change of web site hosting without interfering with the email. That's why many web designing companies control the client's DNS records in a central location.
If the process is incorrectly performed it can result in issues arising with the website and email options. This is obviously cause great concern for clients and can lead to further issues arising at a later date.
To sum up, in configuring the DNS, most web designing companies empower their customers to go past the obvious and embrace the impossible. By doing this it opens up a whole new avenue of services that a web design company can offer to its clients. With this kind of spirit imagine what kind of services that the company can offer to empower their customer's online business.
