In some cases this is because of carelessness: The application does a

notable offenders, continuing to poll the dead address for years after
the server moved.
While yes it often is carelessness - it's been reported by hardcore
development sorts that I trust that there is no standardized API to obtain
the TTL... What needs to get fixed is get[hostbyname,addrinfo,etc] so
programmers have better tools.
