Definition

TTL defines how long DNS resolvers may keep a record in cache before asking again.

What does it mean in practice?

For domains, this term affects registration, transfer, DNS operation, website availability and e-mail routing.

A practical Hostilla.pl example

A domain can be registered correctly while its website or e-mail still fails because delegation or zone records point elsewhere. Use TTL as the starting point, then compare registry data, authoritative DNS and the service destination.

What should you check?

  • domain status, registrar and expiry date
  • authoritative name servers and current delegation
  • A, AAAA, CNAME, MX and TXT records required by the service
  • TTL values and answers from authoritative and caching resolvers
