31.221.102.1是一个公开IP地址，使用者位于英国 英格兰 Staines，其用途是组织，类型是公司/T1。更多详情：31.221.102.1。

A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，第一段号码（字节1）为网络号码，剩下的后三段号码（字节2.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，A类IP地址就由1字节的网络地址和3字节主机地址组成，网络地址的最高位必须是'0'。

A类IP地址范围：1.0.0.0 ~ 127.255.255.255，可用IP地址范围：1.0.0.1 ~ 127.255.255.254。

A类IP地址中网络的标识长度为7位，主机标识的长度为24位，A类网络地址数量较少（2 ^ 7 - 2 = 126个），可以用于容纳1600多万计算机的大型网络（2 ^ 24 - 2 = 16777214个）。
