← DictionaryCNAME
also called canonical name record
A DNS record pointing one name at another name.
Points one address at another address.
What It Is
CNAME is part of Technology, and more precisely DNS. Stated plainly: a DNS record pointing one name at another name.
It is a mechanism rather than an opinion: set up properly it behaves predictably, and set up badly it fails just as predictably. Held that way, the term stays useful instead of turning into decoration.
How It's Used
In practice, CNAME shows up in build decisions, tooling and the plumbing behind a working system. It rarely travels alone — expect it next to DNS Record, A Record and Subdomain. The practical test is whether it is configured, documented and actually working.
Why It Matters
CNAME is one of those items that only becomes visible when it is missing. When it is unclear, small technical debts compound into a rebuild. The businesses that treat it seriously spend less time redoing work.
It is a piece of machinery doing one job in the background. Points one address at another address.
Termshift™
How the meaning shifts depending on who is using it, and where.
In agency and in-house rooms, CNAME means exactly a DNS record pointing one name at another name.
In plain conversation it comes out as points one address at another address.
The Bottom Line
CNAME is not complicated — it is just often left vague. Points one address at another address. Decide it, write it down, move on.
