IPv4的地址域为32比特,可提供232(约40亿)个IP地址。但因将IP地址按网络方案划分成A、B、C三类后,用户可用地址总数明显削减。基于猜想,到2003年~2005年IPv4地址将被用尽

(The address field of IPv4 is 32 bits, which can provide 232 (about 4 billion) IP addresses. However, after the IP addresses are divided into three categories A, B, and C according to the network scheme, the total number of addresses available to users is significantly reduced. Based on conjecture, IPv4 addresses will be exhausted by 2003~2005)
