The Domain Name System (DNS) is the internet's phonebook. It translates human-readable domain names (like google.com) into IP addresses that computers use to communicate. When you type a URL in your browser, DNS servers work behind the scenes to find the correct IP address.
| Record | Purpose | Example |
|---|---|---|
| A | Maps domain to IPv4 address | example.com → 93.184.216.34 |
| AAAA | Maps domain to IPv6 address | example.com → 2606:2800:220:1:... |
| MX | Specifies mail servers | mail.example.com (priority 10) |
| NS | Delegates DNS zone to nameservers | ns1.example.com |
| TXT | Stores text data (SPF, DKIM, verification) | v=spf1 include:_spf.google.com ~all |
| CNAME | Creates alias to another domain | www → example.com |
| CAA | Specifies allowed certificate authorities | 0 issue "letsencrypt.org" |
| SOA | Contains zone administration info | Primary NS, admin email, serial |
DNSSEC adds cryptographic signatures to DNS records, allowing resolvers to verify that responses haven't been tampered with. DNSKEY and DS records are used to establish a chain of trust.
TTL specifies how long DNS records are cached. Lower TTL means faster propagation of changes but more DNS queries. Typical values range from 300 (5 min) to 86400 (24 hours).
