In the following four items, the legal IP address is () a 190.220.5 B 206.53.3.78 C 206.53.312.78 D 123.43.82.220
You have the wrong number. D is wrong because it is connected by commas. I have just finished this problem. Option a is not four
In the C option, 312 is more than 255
The following IP address can represent the IP address of a single computer: a.190.235.0.0 b.123.255.255.255 c.192.169.27.0 d.190.169.0.255
A and C are network addresses because the host number bit is 0
B is the broadcast address, because the host number is all 1
D is the IP address of a computer
Ask a mathematical problem, hope to answer in detail: find all positive integer solutions of equation 123x + 57y = 531
y=(531-123x)/57
Let x = 1,2,3,4
If we calculate y, only if x = 2, y has positive integer solution 5
