In the security evaluation, when testing the black box of a specified target, you need to know the route information of the target to facilitate the bypass testing. Generally, there will always be shared routers in a CIDR block. There will always be many sites that use a route exit closest to the target. You must first find the route during the evaluation.
It is very easy to find the route information. One is visual tracert, which is displayed on the graphic interface. I cannot remember the specific name. Enter the destination http address or IP address to view the route address. If the destination address cannot be reached, you may also need to use a proxy.
Another method is to use the doscommand: tracert Ip or pingpath target. After knowing the IP address of the target route, track the route in the graphic interface and obtain the IP address of the CIDR block.
It's a bit cool. But I think you know it.
