See if a domain resolves and what it points to — IPs, nameservers, propagation status.
| No A/AAAA records | Domain won't resolve — check your host's DNS panel |
| Wrong nameservers | Set at the registrar; must match your hosting provider |
| Propagation lag | DNS changes can take minutes to 48 hours globally |
| ISP caching | Try 1.1.1.1 or 8.8.8.8 to bypass stale ISP records |
| TTL too high | Lower TTL before migrations so changes spread faster |
Usually minutes to hours — up to 48h depending on TTL and resolver caches.
Try dig yourdomain.com or dnschecker.org to see global propagation.
