Abstract:
A method performed by a domain name service client includes storing DNS entries in a local cache; sending a DNS query to another device to obtain an update to one of the DNS entries; determining whether a DNS response is received; and resetting a time-to-live (TTL) timer associated with the one of the DNS entries when the DNS response is not received.
