DNS stands for Domain Name System. Being a naming method for computers, services and resources connected to the internet or any private network, it allows users to associate information to particular domain names.

Businesses and organizations are constantly providing information, services and products using the internet. In fact, most businesses nowadays have online components to stay relevant in the fast changing world of technology. To ensure that they reach their target audience, DNS associates their information, services or products to their names. Improper naming could prove a challenge if the target audience finds it difficult to access such service. As far as the internet is concerned, the issue of security will always surface, thus a source of worry. It is for this reasons that DNS professional services come in handy.

Demand for DNS services is increasing every day. This is because numerous websites are launched everyday, making DNS jobs very relevant. It is for this reason that offering your professional services on Freelancer.com will allow you to create connections with employers who are searching for professional experts who can provide relevant solutions to their pressing needs. As a freelancer, there will always be work for you.

    My startup is picking up steam and I need to get a handle on my emails and communication in general. The first mini project is pretty straight forward; 1. back up all data and email from a GoDaddy open exchange email server 2. Serup a temporary domain 3. Setup new microsoft 365 email accounts for each employee using the new 365godaddy platform OR using microsoft (tbd) 4. Close old email accounts after data back complete and upload data to new email accounts 5. Change temporary domain name back to the original domain from the old godaddy account. I am gerting instructions from Go Daddy as to detailed steps... itll likely take between 5 to 10 hours in total.
