The range of 0.0.0.0/7 is 0.0.0.0 - 1.255.255.255.

The range of 1.0.0.0/8 is 1.0.0.0 - 1.255.255.255.



AFAIK, 0.0.0.0/8 (0.0.0.0 - 0.255.255.255) is not usable. So, do these represent the same range practically?



ip route add 0.0.0.0/7 dev eth1 # 1
ip route add 1.0.0.0/8 dev eth1 # 2


Is the effect the same?

Clearly these are not the same.



However, nothing in 0.0.0.0/8 is a valid destination address, so the effect of each route would be the same. Attempts to connect to anything in 0.0.0.0/8 would just fail as always with an Invalid argument error, while attempts to connect to 1.0.0.0/8 would be routed as specified.

It is a team of 2: just I and my supervisor. Diurnally, I am posed with a "bug of the day" to get out of this C++ code. My supervisor generally gives me about 15-30 minutes to solve it and then accosts me about whether or not the task is completed and then rinses and repeats this until the end of the day.

This Kransekake is a traditional Scandinavian baker's confection. Confectionery is the art of making confections , which are food items that are rich in sugar and carbohydrates. Exact definitions are difficult. [1] In general, though, confectionery is divided into two broad and somewhat overlapping categories, bakers' confections and sugar confections. [2] Bakers' confectionery, also called flour confections , includes principally sweet pastries, cakes, and similar baked goods. Sugar confectionery includes candies ( sweets in British English), candied nuts, chocolates, chewing gum, bubble gum, pastillage, and other confections that are made primarily of sugar. In some cases, chocolate confections (confections made of chocolate) are treated as a separate category, as are sugar-free versions of
