DNS Propagation
The delay before a DNS change is seen everywhere, as cached old records expire across resolvers.

DNS propagation is the lag between making a DNS change and that change being visible everywhere on the internet. It happens because resolvers around the world cache the old answer until its TTL expires, so a new record or nameserver update rolls out gradually rather than instantly — anywhere from minutes to a couple of days. There is no global "DNS" to update at once; propagation is just caches timing out. The practical fix is to lower the TTL ahead of a planned change. None of this touches a domain's ownership: tokenization changes who controls the name on-chain, not how quickly DNS edits spread. Sources: Cloudflare TTL glossary; RFC 1035.
