Step-by-Step Guide
1 Understand DNS Basics
DNS is like the internets phone book, translating human-readable domains to IP addresses. Records are managed through your registrar or DNS provider.
Pro Tips:
- Use a reliable DNS provider
- Consider DNS redundancy
2 Common Record Types
A records point to IPv4 addresses, AAAA to IPv6, CNAME creates aliases, MX handles email, and TXT stores text data like SPF records.
Pro Tips:
- A and CNAME are most common
- Cant mix CNAME with other records at apex
3 Manage TTL and Propagation
TTL (Time To Live) controls how long records are cached. Lower TTL before changes to speed propagation, raise after for better caching.
Pro Tips:
- Lower TTL before migrations
- Check propagation with dig or nslookup
