Abstract
A method of dynamically updating DNS information in an IP network. A first entity of the IP network, distinct from DNS servers of the IP network, receives a request from a second entity of the network, likewise distinct from the DNS servers but possessing a copy of DNS information, constituting a record in at least one DNS server of the IP network. The first entity responds to the request by sending a message to the second entity, including an indication about the need to modify the copy. On receiving the message, the second entity determines whether the indication includes at least one additional instruction. If so, the second entity: performs a DNS interrogation, and on receiving a response, modifies its copy of the DNS information based the response and the additional instruction; or modifies its copy of the DNS information based on the additional instruction without performing a DNS interrogation.
