效果演示：

源码如下：

import random


class Random_IP:
    def getip(self):
        ip1 = random.randint(0,254)
        ip2 = random.randint(0,254)
        ip3 = random.randint(0,254)
        ip4 = random.randint(0,254)
        return str(ip1)+'.'+str(ip2)+'.'+str(ip3)+'.'+str(ip4)


if __name__== '__main__':
    random_ip = Random_IP()
    print(random_ip.getip())
