Round Robin DNS distributes traffic by creating multiple A records pointing to different server IPs. It's free and simple but provides no health checking or failover, if a server dies, DNS still routes traffic to it. Best for stateless applications needing quick capacity scaling.
Domain not resolving? Learn the causes, fixes, and troubleshooting steps to restore DNS quickly.
Understand DNS propagation, how long it takes, and how to speed it up. Learn how DNS caching, TTL, and nameservers affect your domain updates.
Learn the difference between domain masking and redirects. Discover which option is better for SEO, user trust, and website performance in 2026.
Compare DNS-over-HTTPS (DoH) vs DNS-over-TLS (DoT). Learn which protocol is faster, more private, and easier to deploy in 2026.
DNSSEC adds cryptographic signatures to DNS records, preventing spoofing and cache poisoning attacks. It secures the DNS route while SSL secures web traffic, both are needed. Enable by adding DS records at your registrar linking to your DNS provider's signing keys.
A records point domains to IPv4 addresses (e.g., 192.0.2.1); AAAA records point to IPv6 (e.g., 2001:0db8:85a3::8a2e:0370:7334). Configure both for dual-stack compatibility as mobile carriers and cloud providers migrate to IPv6.
Misconfigured nameservers can break websites, email delivery, and SSL validation. Learn why DNS errors happen and how to prevent costly downtime.
Learn how to audit your domain for hidden DNS, email, SSL, and hosting risks before they cause outages or security issues.
Why do some users still see the old IP after a DNS change? Learn how DNS caching works, how long propagation really takes, and how to fix stale cache issues
Changing nameservers can break websites and email if you miss records. Learn what changes, what stays, and a safe step-by-step migration checklist.
