In one aspect, a method for preventing data packet losses when updating of an address table that is stored in a computer of a local area network and comprises allocations of computer addresses valid in the local area network to computer addresses valid in the Internet to mail data packets is provided. Accordingly, an address allocation stored in the address table is updated after an expiration of a timer. The computer requests the computer address valid in the local area network regarding the available computer address valid in the Internet for the address allocation. The determined computer address valid in the local area network is entered into the address allocation and the marking for the address allocation is cleared. Thus, an address allocation available is kept even when the address allocation is updated, resulting in preventing data packet losses and maintaining the quality of the local area network.
