What Is DNS (Domain Name System)?
The Domain Name System (DNS) is the internet's phone book — it translates human-readable domain names (like example.com) into IP addresses (like 93.184.216.34) that computers use to connect to each other. Modern security enhancements like [DNS-over-HTTPS](/glossary/dns-over-https) and [DNSSEC](/glossary/dnssec) add encryption and verification to this process.
Why It Matters
Every time you type a domain name into your browser, DNS is what makes it work. Without DNS, you’d need to memorize IP addresses like 93.184.216.34 instead of domain names like example.com.
For domain forwarding, DNS is the starting point. Before Domain Forward can redirect your domain, your DNS records need to tell the internet to send traffic to our servers. This is usually just two record changes: an A record and a CNAME record.
How It Works
- You type
example.comin your browser - Your browser asks a DNS resolver: “What IP address is
example.com?” - The resolver checks its cache, then queries nameservers up the chain
- Eventually it reaches the authoritative nameserver for
example.com - That nameserver responds with the IP address from the A record
- Your browser connects to that IP address
This entire process takes milliseconds and happens before any web page — or redirect — loads.
Key DNS Record Types
| Record | Purpose | Used By Domain Forward? |
|---|---|---|
| A Record | Maps domain to IPv4 address | Yes — points apex domain to our servers |
| AAAA Record | Maps domain to IPv6 address | Optional |
| CNAME | Maps subdomain to another domain | Yes — points www to our servers |
| MX Record | Routes email | No — untouched |
| TXT Record | Stores text data (SPF, DKIM, verification) | No — untouched |
| SRV Record | Maps specific services (ports) | No — untouched |
| CAA Record | Controls which CAs can issue certificates | No — untouched |
| NS Record | Delegates to nameservers | No — managed by registrar |
DNS and Domain Forwarding Setup
To set up forwarding with Domain Forward, you typically:
- Add your domain in the Domain Forward dashboard
- Update your A record to point to Domain Forward’s IP
- Update your CNAME record for
wwwto point to Domain Forward - Wait for DNS propagation (usually under an hour)
Your email, TXT records, and other DNS records stay exactly as they are. You can also verify your setup with a reverse DNS lookup. See our DNS setup guide for step-by-step instructions.

asked questions
Your DNS records tell the internet where to send traffic for your domain. To use Domain Forward, you point your DNS records to our servers — so when someone visits your domain, the request reaches us and we perform the redirect.
DNS changes propagate across the internet in minutes to 48 hours, depending on the TTL value of your current records. Most changes take effect within 1-2 hours. See DNS propagation for details.
Only if you change MX records (which handle email). Domain Forward only requires changes to A and CNAME records, which handle web traffic. Your MX records stay untouched.
