Understanding DNS Records
Different record types serve different purposes in the Domain Name System
A Record
Maps domain to IPv4 address
192.0.2.1Use: Website hosting
AAAA Record
Maps domain to IPv6 address
2001:db8::1Use: IPv6 websites
MX Record
Mail exchange servers
mail.example.comUse: Email delivery
TXT Record
Text information
v=spf1 include:_spf.google.com ~allUse: SPF, verification
CNAME Record
Canonical name alias
www β example.comUse: Subdomain redirects
NS Record
Name servers
ns1.example.comUse: DNS authority
Frequently Asked Questions
Why are DNS changes not showing immediately?βΌ
DNS changes take time to propagate because DNS resolvers cache records based on TTL (Time To Live) settings. Lower TTL = faster propagation. Most ISPs refresh their cache every few hours.
How can I speed up DNS propagation?βΌ
Lower your TTL to 300-600 seconds before making changes. Clear your local DNS cache (ipconfig /flushdns on Windows, sudo dscacheutil -flushcache on Mac). Use our checker to monitor progress.
What is the difference between authoritative and recursive DNS?βΌ
Authoritative DNS servers hold the original DNS records for your domain. Recursive DNS servers (like your ISP or Google 8.8.8.8) query authoritative servers and cache results for end users.
Why do different locations show different results?βΌ
DNS propagation is not instant worldwide. Different DNS providers refresh their caches at different times. Our checker shows the current state from multiple global locations.
What should I do if propagation is taking too long?βΌ
Check your TTL settings before the change, verify DNS records are correct, contact your DNS provider if issues persist, and use our checker to monitor multiple locations.
