A CNAME record or Canonical Name record is a type of resource record in the Domain Name System (DNS) that specifies that the domain name is an alias of another, canonical domain name. Here "canonical" usually means: a more generally accepted or standard name.
This helps when running multiple services (like an FTP server and a webserver; each running on different ports) from a single IP address. Each service can then have its own entry in DNS (like ftp.example.com and www.example.com).
RTCP (RFC 3550) CNAMEs are not the same as DNS CNAMEs; they are clarified in RFC 6222.

Famous quotes containing the word record:
“... many of the things which we deplore, the prevalence of tuberculosis, the mounting record of crime in certain sections of the country, are not due just to lack of education and to physical differences, but are due in great part to the basic fact of segregation which we have set up in this country and which warps and twists the lives not only of our Negro population, but sometimes of foreign born or even of religious groups.”
—Eleanor Roosevelt (1884–1962)
