1. A method for processing a request for anonymization of a source IP address of an IP packet transmitted by a transmitting device to a recipient device via a communications network, said transmitting device being connected to said network via a network terminal apparatus, said method being carried out by an anonymization device, which is positioned for cutting the flow between said network terminal apparatus and said recipient device, said method comprising:
receiving said IP packet;
a verification for establishing whether said source IP address of said packet has to be anonymized or not;
if a result of said verification is negative, of routing said IP packet to said recipient device;
if the result of said verification is positive and if said anonymization device has an address translation function:
replacing said source IP address with an IP address of said anonymization device; and
routing said IP packet to said recipient device;
if the result of said verification is positive and if said anonymization device does not have an address translation function, routing said IP packet to said recipient device via an apparatus of said network having an address translation function.
