<en_message>One of the subnets has a poorly crafted subnet. There are two ways to represent subnets. The "dot-decimal" notation (255.255.255.0) and CIDR (/24).
Here, we are using a subnet of 255.255.255.129. The 129, in binary, is 10000001. That trailing 1 is the problem. It basically puts the odd numbers in one subnet and the even numbers in the other subnet. While it is possible to get networks to function with a terrible subnet mask like this, do not do it. Use numbers that are properly represented by CIDR notation. Basically, in binary, you want a bunch of 1s, followed by 0s. (111000), not 1s and 0s intermingled. (10101). CIDR (/25) represents the number of 1s, and the rest are 0.
To solve this puzzle, find the IP Addresses that have the /? and change the subnet to something that works. Then, try pinging.</en_message>

L'un des sous-réseaux a un sous-réseau mal conçu. Il y a deux façons de représenter les sous-réseaux. La notation "point-décimal" (255.255.255.0) et CIDR (/ 24).
Ici, nous utilisons un sous-réseau de 255.255.255.129. Le 129, en binaire, est 10000001. Ce trailing 1 est le problème. Il met fondamentalement les nombres impairs dans un sous-réseau et les nombres pairs dans l'autre sous-réseau. Bien qu'il soit possible d'obtenir des réseaux pour fonctionner avec un masque de sous-réseau terrible comme celui-ci, ne le faites pas. Utilisez des nombres correctement représentés par la notation CIDR. Basically, in binary, you want a bunch of 1s, followed by 0s. (111000), not 1s and 0s intermingled. (10101). CIDR (/25) represents the number of 1s, and the rest are 0.
