A DNS record pointing a domain to a specific IP address.
Points your domain at a numbered server.
What It Is
In the BWH map, A Record lives under Technology — DNS. The working definition is simple: a DNS record pointing a domain to a specific IP address.
It is a mechanism rather than an opinion: set up properly it behaves predictably, and set up badly it fails just as predictably. Keep it that plain and it will still be true in twelve months.
How It's Used
A Record comes up in build decisions, tooling and the plumbing behind a working system. It is usually discussed together with DNS Record, CNAME and Hosting. The practical test is whether it is configured, documented and actually working.
Why It Matters
Getting A Record wrong is expensive in a quiet way. When it is unclear, small technical debts compound into a rebuild. It is worth pinning down before anyone builds on top of it.
Think of plumbing. Nobody admires it, everybody notices when it leaks. Points your domain at a numbered server.
Termshift™
How the meaning shifts depending on who is using it, and where.
Practitioners use A Record as shorthand and expect no explanation — a DNS record pointing a domain to a specific IP address.
Outside the industry, most people would just say: points your domain at a numbered server.
The Bottom Line
Keep A Record plain: points your domain at a numbered server. That is the version that holds up in a real project.
