Our school's internal network addresses are 172.168.8. * this segment, I checked the, 172.168.8.1 belongs to the United States, not private address, but our school internal why can?

CodePudding user response:

Can match, also can use in normal, but in the following scenario will be unreachable network fault (correct routing covered by network routing cause) :
1. Access to the public in the true host in the network segment.
2. Access to public resources, through the network segment,

Only when meet the following conditions, in the network environment using public network address does not have any problem:
1. The public network address section is assigned to your normal way;
2. Network planning without error,
(in fact, in this case, your network is the equivalent of an autonomous region)

Again, you are now all this address planning as design caused by half a bucket of water,

Can be used as private IP paragraph, but there is a limitation, as follows:

Internal network need to access the Internet in your school, these 172.168.8. * segment of computer need to get to the Internet, and to access the site or application domain names corresponding IP is in 172.168.8. * this segment, the domain name and IP is unavailable, characterized by network unable to connect,
