子网掩码、ip地址、主机号、网络号、网络地址、广播地址（国外英文资料） A few words master the subnet mask, IP address, host number, network number, network address, and broadcast address 191.172.16.10.33/27/27 which means that the subnet mask is 255.255.255.224 or 27 full 1 2. From the subnet mask 255.255.255.252 concluded its network to 30, so only the remaining two slots, host a full zero for the network address, host 1 for the broadcast address, all of them, and the rest of the host number on the scope of the host address Public address is run by the Inter NIC (Internet Network Information Center). These IP addresses are assigned to the organization that is registered and applied to the Inter NIC. Direct access to the Internet. Private address is a non-registered address that is specifically used within the organization. Private IP address is not possible to communicate directly with WAN, or USES the frame for communication (such as FR frame relay, in HDLC, PPP) or routing of the NAT function to the private network address translation as a public IP address The following list of internal private addresses is listed A is 10.0.0.0 -- 10.255.255.255 Class B 172.16.0.0 -- 172.31.255.255 C class 192.168.0.0 -- 192.168.255.255 And let me give you an example of what happens in CCNA: First of all, lets look at an examination of the common questions: a hosts IP address is 202.112.14.137, mask 255.255.255.224, require the calculated the network address of the host in the network and broadcast address. The conventional approach is to convert this host address and subnet mask into binary Numbers, both of which are logical and operable to get the network address. Actually you want to think about it, you can get another method: the mask 255.255.255.224 contains the IP address of the 256-224 = 32 (including network address and broadcast address), so have this mask network address must be a multiple of 32. Is the beginning of the subnet an IP address and network address, the broadcast address is end, usable host
