Many sites use an alias in their Domain Name Server (DNS) system so they can assign a familiar name to the site. Rather than connecting to a host using its actual host name (for example, gyro.ipswitch.com) or IP address, it may be easier for users to remember or guess a name like ftp.ipswitch.com.
To create an alias, add an entry in your DNS records like the one below:
ftp IN CNAME gyro.ipswitch.com
Users could then log on to ftp.ipswitch.com. The alias also allows you to move your site to another host without changing the hostname.
For more information, consult the documentation for your DNS system or contact your network administrator.
