Alias name in DNS server allows administrators to assign a user friendly name for any host based on the domain name. Alias names are mostly used for web servers where real host names are complicated enough to be distributed to external users. With the help of alias names administrators can specify a unique user-friendly name which can be mapped with the DNS server and can be distributed among both internal and external users to make them access the website easily and remember the name as well. Creation of alias names in DNS server is a simple process provided a corresponding Host (A) record is available for which the alias name is being created. As a DNS administrator in Windows server 2008 environment if you want to create alias name for any Host (A) record you need to follow the steps given below:
