Method for an enhanced management of Internet Protocol, IP, addresses in a telecommunications network, the telecommunications network comprising a backbone, and a plurality of access nodes in order to provide IP connectivity to a plurality of customer premise equipments connected to the telecommunications network via the access nodes, wherein the IP addresses are provided to the access nodes by an IP address manager, wherein the number of IP addresses, required by one access node of the plurality of access nodes, varies in time, wherein, as a result, IP addresses are allocated to and de-allocated from the one access node of the plurality of access nodes by the IP address manager dependent on the variation in time of the IP addresses requested by the access node, wherein the method comprises the following steps: -- in a first step, the one access node of the plurality of access nodes, or the IP address manager detects that additional IP addresses are required or will be required for the customer premise equipments connected or possibly going to be connected to the telecommunications network via the access node, -- in a second step, the one access node of the plurality of access nodes sends an IP addresses allocation request to the IP address manager for allocation of additional IP addresses, the IP addresses allocation request including an indication related to the increase per time interval of required IP addresses at the access node, wherein the indication is related to the speed of increase of required IP addresses at the one access node of the plurality of access nodes, or the IP address manager detects the increase per time interval of required IP addresses at the access node, wherein the IP address manager detects the speed of increase of required IP addresses at the access node, -- in a third step, IP addresses are allocated to the one access node of the plurality of access nodes by the IP address manager dependent on the IP addresses allocation request, wherein, depending on -- either the IP addresses allocation request, and depending on the indication related to the speed of increase of required IP addresses at the one access node of the plurality of access nodes, or -- the IP address manager detecting the speed of increase of required IP addresses at the access node, IP addresses are additionally allocated to the access node by the IP address manager, the additionally allocated IP addresses comprising: -- a variable number of blocks of IP addresses or -- a block of IP addresses comprising a variable number of IP addresses, wherein -- upon reception of a new IP address request at the one access node of the plurality of access nodes, from a customer premise equipment at least indirectly connected to the access node, and -- in case of at least one available IP address in a plurality of blocks of IP addresses allocated to the access node, an available IP address in a fixed block of IP addresses is prioritized to be used for the new IP address request over an available IP address in dynamic block of IP addresses, and an available IP address in a more completely used dynamic block of IP addresses is prioritized to be used for the new IP address request over an available IP address in a less completely used dynamic block of IP addresses. -- in a first step, the one access node of the plurality of access nodes, or the IP address manager detects that additional IP addresses are required or will be required for the customer premise equipments connected or possibly going to be connected to the telecommunications network via the access node, -- in a second step, the one access node of the plurality of access nodes sends an IP addresses allocation request to the IP address manager for allocation of additional IP addresses, the IP addresses allocation request including an indication related to the increase per time interval of required IP addresses at the access node, wherein the indication is related to the speed of increase of required IP addresses at the one access node of the plurality of access nodes, or the IP address manager detects the increase per time interval of required IP addresses at the access node, wherein the IP address manager detects the speed of increase of required IP addresses at the access node, -- in a third step, IP addresses are allocated to the one access node of the plurality of access nodes by the IP address manager dependent on the IP addresses allocation request, wherein, depending on -- either the IP addresses allocation request, and depending on the indication related to the speed of increase of required IP addresses at the one access node of the plurality of access nodes, or -- the IP address manager detecting the speed of increase of required IP addresses at the access node, -- a variable number of blocks of IP addresses or -- a block of IP addresses comprising a variable number of IP addresses, -- upon reception of a new IP address request at the one access node of the plurality of access nodes, from a customer premise equipment at least indirectly connected to the access node, and -- in case of at least one available IP address in a plurality of blocks of IP addresses allocated to the access node,
