1. A method for allocating an identifier to a first client node of a client domain, at least one traffic management server being associated with the client domain, the method being implemented by an allocation device and comprising:

receiving a request from the first client node for allocating a client node identifier to the first client node, the request comprising at least one item of information for identifying the first client node and the first client node being able to manage the traffic associated with the client domain in order to protect the client domain against a computing attack;

obtaining a list of client node identifiers already allocated to client nodes active at least in the client domain;

allocating to the first client node a client node identifier not belonging to the list obtained;

recording in a local memory an association between the allocated client node identifier and the item of information for identifying the first client node;

sending a response to the first client node, comprising the allocated client node identifier; and

sending to the at least one traffic management server a request for recording in association with the domain the client node identifier allocated to the first client node in the domain.
