The company has two servers A (218.34.45.65) and B (218.34.45.66 ). All are placed on the hosting server!
Server configurations of known:
IP: 218.34.45.65
Subnet mask: 255.255.255.66
Default Gateway: 218.34.45.10
DNS1: 123.34.35.45
DNS2: 123.34.35.1
You need to reconfigure the static IP address of server B based on server A to facilitate Internet access to this server.
Server B is in centos 5.7
IP: 218.34.45.66 // only this location is changed
Subnet mask: 255.255.255.66
Default Gateway: 218.34.45.10
DNS1: 123.34.35.45
DNS2: 123.34.35.1
Problem:
1. after modification, I found that server B can PING server A without using the internet. why? Is it related to the firewall?
2. Generally, the subnet mask is 255.255.255.0. why is there 255.255.255.255.255.66?
3. subnet mask, default gateway, and whether DNS is provided by hosted servers
4. from the above configuration, whether these network cables are directly connected to the server, but not through the router, because I understand the common practice is to use an internal IP address (such as 192.168.0.10 ), then, you can map out the vro to allow external users to access the 192.168.0.10 server through the static IP address.
Reply to discussion (solution)
You give the router channel address, not the host ip address.
The same IDC is not equal to the same route access. Specifically, you need to ask the IP address allocation of the IDC.
Haha, you have not solved this problem! Do not close the post!
