DNS Propagation

Check whether DNS records for a domain have propagated across the world's key resolvers.

Protocol and path are stripped automatically. Query is sent to 6 DNS servers in parallel.

DNS Propagation Checker Online

The DNS Propagation tool on 101IP checks whether your domain's DNS records have propagated across the world's key resolvers: Google, Cloudflare, Quad9, OpenDNS, AdGuard and Yandex DNS. Queries are executed in parallel via DoH (DNS over HTTPS).

Why check DNS propagation

after migrating a site to a new hosting provider or changing the IP address;
when switching DNS providers or updating the domain's NS records;
when setting up new A, AAAA, MX or TXT records;
to diagnose the situation where the site opens for you but not for others.

How long does DNS propagation take

Usually from a few minutes up to 48 hours, depending on the TTL of the old records and the caching policies of resolvers. If all servers still show the old value, wait for the TTL to expire.
