9. Given an address of 18.104.22.168 and a prefix mask of /25, how many networks can be addressed,and how many hosts can exist on each network? Write the first and last possible subnets in binary and decimal notation.
For the network address of 22.214.171.124, the subnet mask of 255.255.255.128 would enable you
to address 510 subnets with 126 hosts on each subnet. This complies with the subnetting rule
of not allocating addresses with all 0s or all 1s. The following table illustrates the first and last
subnet in their binary and decimal notation formats.
я так понимаю это ошибка ? и сетей будет 2 , а не 510 ?
510 будет в случае такой маски 255.255.128.0 /17
