• 拨号上网的一定有特殊的IP段。 - bluesea (124 bytes) 2008-12-02, 16:30:13 (280263)
  • no, just those dial-up servers are well known. (无内容) - steven (0 bytes) 2008-12-02, 16:40:03 (280272)
    • 不是动态分配IP 的？ - bluesea (21 bytes) 2008-12-02, 16:46:22 (280275)
      • They all use NAT, the outside world can only see the server. (无内容) - steven (0 bytes) 2008-12-02, 17:05:43 (280285)
        • well, many T1 lines for small business Co use NAT too - JJZ (65 bytes) 2008-12-02, 18:53:52 (280312)
