How long does a DNS change take?

DNS changes don’t reach DNS servers worldwide instantly — each server keeps the old data for the TTL period. This is called DNS propagation.

• DNS record changes: usually from a few minutes to 1–2 hours.
• Nameserver changes: usually 1–4 hours, up to 24–48 hours at most.

To speed up propagation

1. Clear your browser cache or open the site in a private (incognito) window.
2. Clear the DNS cache on your computer: ipconfig /flushdns on Windows, sudo dscacheutil -flushcache on macOS.
3. Turn off Wi-Fi on your phone and check over mobile data.
