DNS Propagation Checker
Check your domain's DNS propagation across global servers
Frequently Asked Questions
What is DNS propagation?
DNS propagation is the process by which changes to a domain's DNS records spread across all DNS servers worldwide. When you change a DNS record, servers in different locations may take from minutes to 48 hours to update their caches with the new value.
How long does DNS propagation take?
DNS propagation can take from a few minutes to 48 hours, depending on the TTL (Time to Live) configured on the records. Records with low TTL (300s) propagate faster. In practice, most major DNS providers like Google and Cloudflare update within minutes.
What do DNS record types mean?
The main types are: A (IPv4 address), AAAA (IPv6 address), CNAME (alias), MX (mail server), NS (nameservers), TXT (free text, used for SPF/DKIM/DMARC verification), SOA (authority information), CAA (SSL certificate authorization), and SRV (service location).
Why do some servers show different results?
Different results may indicate that propagation is still in progress, the DNS server has stale cache, or GeoDNS configurations return different IPs by region. Servers with timeout may be blocking external queries or experiencing network issues.
How to speed up DNS propagation?
To speed up propagation: 1) Lower the TTL of records before making changes (e.g., 300 seconds). 2) After the change, wait for the previous TTL time. 3) Use DNS providers with anycast network like Cloudflare or Google Cloud DNS. 4) Clear local DNS cache with 'ipconfig /flushdns' (Windows) or 'sudo dscacheutil -flushcache' (Mac).
