Frequently Asked Questions
What is a DNS lookup?
A DNS lookup translates a domain name (like example.com) into an IP address that computers use to locate servers. It queries DNS records including A, AAAA, CNAME, MX, TXT, and NS records.
What are the different DNS record types?
A records map to IPv4 addresses, AAAA to IPv6, CNAME creates aliases, MX directs email, TXT stores text data (SPF, DKIM), NS specifies nameservers, and SOA contains zone authority information.
How does DNS affect website speed?
DNS resolution adds 20-120ms to every new connection. Slow DNS can significantly impact page load times. Use fast DNS providers, enable DNS prefetching, and keep TTL values reasonable (300-3600 seconds).
