Does anyone know
Refer to the answer 1：
What do you think , Can simply rely on ip Address to roughly calculate .
Refer to the answer 2：
Refer to the answer 3：
See how many hosts can be accommodated in the subnet of a small network , The general router is 254 platform , But if you want to say coverage , See how long your network cable can be pulled ,wifi How strong the signal is , Theoretically , As long as the signal is strong enough , Global coverage is no problem , As for how many can be connected at the same time , Then use subnet mask and ip Address to calculate
Refer to the answer 4：
Refer to the answer 5：
LAN usually uses private network IP A network where addresses are interconnected , The private network address is 192.168.0.0/16,172.16.0.0/16-172.16.31.0.0/16,10.0.0.0/24.
The Internet is through the public network IP Address interconnection , Local area networks need to be interconnected through the public network IP Address translation at the Internet exit .
Of course, this is now IPV4 The status quo of , because IPV4 The number of addresses is limited .
After the IPV6 Theoretically, any terminal can be assigned to ipv6 Public address .IPV4 The address is 32 position ,IPV6 The address is 128 position , In exaggerated terms, every grain of sand on the earth can be allocated one IPv6 Address .
