Hi,

How do I correctly short-hand a block of IP addresses ranging from
xxx.xxx.xxx.105 to .110? My ISP provided a netmask of 255.255.255.248,
which I assume translates into xxx.xxx.xxx.105/29. However, shouldn't that
be /27?

Any input greatly appreciated.

Mike

why /27? Who says this?

248 in binary is 11111000

decimal 255.255.255.248
binary 11111111 11111111 11111111 11111000

so /29 is correct

or am i too drunk to understand your question?
