What Is DNS?
A plain-English guide to DNS, the records that make it work, and how Outbound.com can manage it for you.
Every website — including your landing pages — lives on a server somewhere.
DNS (the Domain Name System) is what connects your domain name, like
yourbusiness.com, to that server, so when someone types your address or
clicks your ad, they actually reach your site.
Think of DNS as the internet's phone book: it turns a name people can remember into the numeric address computers use to find each other. You don't need to be technical to run a great business online — but understanding the basics helps you see how your website, landing pages, and email all fit together.
In one sentence: DNS points your domain name to the right places — your website, your landing pages, and your email — so everything works when a customer looks you up.
How it works
A customer looks you up
Someone types your domain or clicks your ad. Their device asks DNS a simple
question: "Where does yourbusiness.com actually live?"
DNS checks your records
DNS reads your records — the settings that say which server hosts your site and where your email should go — and returns the answer.
Your page loads
The customer's browser connects to that server and your page appears, usually in a fraction of a second.
When we build a landing page or host your website, this is the connection that has to be pointed correctly. If DNS isn't set up right, customers can't reach your site — even if the site itself is perfect.
The different DNS records
Your DNS settings are made up of individual records, each with a specific job. These are the ones you're most likely to run into:
| Record | What it does |
|---|---|
| A | Points your domain to the server that hosts your website or landing page — the record that gets your site online. |
| CNAME | Points one name to another, like making www.yourbusiness.com load the same site as yourbusiness.com, or connecting a subdomain to a host. |
| MX | Directs your email to your email provider, so messages sent to you@yourbusiness.com actually arrive. |
| TXT | Holds short text notes used to verify you own the domain and to protect your email from being spoofed by scammers. |
| NS | Names the service in charge of your DNS — the control panel where all these records live. |
You may also come across an AAAA record (the newer version of an A record) and a TTL value (how long a record is remembered before it's looked up again). And when you change a record, it can take anywhere from a few minutes to a full day to take effect everywhere — this delay is called propagation.
Why DNS matters for your business
Two of the most common things we do for service businesses depend on DNS being set up correctly:
- Landing pages — When we build landing pages for your Google Ads, DNS is how your domain (or a subdomain of it) points to the page, so it loads under your own brand. See Connect Your Custom Domain for the step-by-step.
- Website hosting — If we host your website, DNS connects your domain to where the site lives so customers reach it reliably.
Get DNS wrong and the symptoms are painful: a site that won't load, a landing page that shows an error, or email that quietly stops arriving. Get it right and it's completely invisible — which is exactly what you want.
Let us manage it for you
DNS is powerful but unforgiving — a single wrong record can take your website or email offline. Most business owners would rather not touch it, and that's completely reasonable.
DNS Management is an available add-on. With it, the Outbound.com team manages your DNS on your behalf: we make sure your domain points to the right place, keep your landing pages and website online, look after your email records, and handle any changes safely — so you never have to log into a DNS control panel or worry about breaking something.
