c# - IPAddress.[Try]Parse解析192.168为192.0.0.168

Question

我有以下场景:

IPAddress ip;
IPAddress.TryParse("192.168", out ip);    
if(ip == null){//do something with IP}

我预计解析会失败，但它被解析为“192.0.0.168”。我在这里错过了什么？ (IPAddress.Parse 作用相同)

来自 Parse 的文档:

The number of parts (each part is separated by a period) in ipString determines how the IP address is constructed. A one part address is stored directly in the network address. A two part address, convenient for specifying a class A address, puts the leading part in the first byte and the trailing part in the right-most three bytes of the network address. A three part address, convenient for specifying a class B address, puts the first part in the first byte, the second part in the second byte, and the final part in the right-most two bytes of the network address. For example:

Number of parts and example ipString | IPv4 address for IPAddress
1 -- "65536"                         | 0.0.255.255
2 -- "20.2"                          | 20.0.0.2
2 -- "20.65535"                      | 20.0.255.255
3 -- "128.1.2"                       | 128.1.0.2
