Understanding nameservers and DNS delegation fundamentals
Process of transferring DNS authority from parent domain to child domain through NS records and glue records.
Example: yourdomain.com → ns1.yourdomain.comDNS servers that have complete and up-to-date information about a domain's DNS records and can provide authoritative answers.
Primary source of DNS informationA records that provide IP addresses for nameservers in the same domain, preventing circular dependencies in DNS resolution.
Required for nameservers in same domainEssential guidelines for optimal nameserver setup and management
Always use at least 2 nameservers for redundancy. This ensures your domain remains accessible if one nameserver fails.
Recommended: 2-4 nameservers from different providersPlace nameservers in different geographic locations to improve global DNS resolution speed and reliability.
Use nameservers from different continents when possibleSet appropriate TTL values for your NS records. Lower TTLs allow faster changes but increase DNS query load.
Typical range: 300-3600 seconds (5 minutes to 1 hour)Create glue records for nameservers in the same domain to prevent circular dependencies and improve resolution.
Required when nameserver hostname is in the same domainImplement monitoring for nameserver availability and performance. Set up alerts for downtime or slow responses.
Use tools like Pingdom, UptimeRobot, or custom monitoringEnable DNSSEC for nameserver security, use strong authentication, and regularly update nameserver software.
Protect against DNS spoofing and cache poisoning attacks
