204.155.20.1是一个公开IP地址，使用者位于日本 Tokyo Metropolis Tokyo，其用途是商业，类型是公司/T1。更多详情：204.155.20.1。

C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，前三段号码（字节1.字节2.字节3）为网络号码，剩下的后一段号码（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，C类IP地址就由３字节的网络地址和1字节主机地址组成，网络地址的最高位必须是'110'。

C类IP地址范围：192.0.0.0 ~ 223.255.255.255，可用IP地址范围：192.0.0.1 ~ 223.255.255.254。

C类IP地址中网络的标识长度为21位，主机标识的长度为8位，C类网络地址数量较多（2 ^ 21 = 2097152个），适用于小规模的局域网络，每个网络最多只能包含254台计算机（2 ^ 8 - 2 = 254个）。
