How to check whether a domain’s DNS records have propagated globally?
Checking DNS record propagation
What is DNS propagation?
After DNS records are changed, it takes time (usually up to 24–48 hours) for the updates to spread across DNS servers worldwide.
Checking via online services
Enter the domain → select the record type → run the check.
If the IP address is the same in different countries, the records have propagated.
Via the command line
nslookup domain.com
or
dig domain.com
Reasons for missing DNS resolution
- TTL has not expired
- Incorrect NS servers
- Error in the DNS record
- DNS server is unavailable
- Local cache
How to fix
- Verify DNS records
- Check NS servers
- Clear the DNS cache
- Wait until the TTL expires
