170.121.55.1是一个公开IP地址，使用者位于美国 哥伦比亚特区 Washington，其用途是政府，类型是公司/T1。更多详情：170.121.55.1。

B类IP地址是指：在IP地址的四段号码（例如：字节1.字节2.字节3.字节4）中，前两段号码（字节1.字节2）为网络号码，剩下的后两段号码（字节3.字节4）为本地计算机的号码。

如果用二进制表示IP地址的话，B类IP地址就由2字节的网络地址和2字节主机地址组成，网络地址的最高位必须是'10'。

B类IP地址范围：128.0.0.0 ~ 191.255.255.255，可用IP地址范围：128.0.0.1 ~ 191.255.255.254。

B类IP地址中网络的标识长度为14位，主机标识的长度为16位，B类网络地址适用于中等规模的网络（2 ^ 14 = 16384个），每个网络所能容纳6万多台计算机（2 ^ 16 - 2 = 65534个）。
