That's all about how the 32 address bits are being distributed between network address and host address. /18 means the most significant 18 bits designate the network part, and the remaining 14 bits the host part. 192.168.0.0/18 will give you 4 subnets with 16384 (= 2^14) addresses each:
For minimum 1000 devices you'll need 10 bits to accommodate 1024 addresses, so the internal /22 netmask comes in handy (32 bit - 22 bit = 10 bit addresses in each subnet). The 16 (= 2^4; 4 = 14 - 10) sub-subnet ranges are
, the 9th of which - depending how you count them, starting from 0 or 1 - is the network address 192.168.32.0 with the broadcast address 192.168.35.255 (hopefully, as my binary calculus has become somewhat rusty).
Before I even attempt this, is it possible to grep for a pattern, maybe a partial sentence like "go to page 3", assign that to a variable and then use awk or something to pull out the 3 and assign it to a variable? So first I would have
Gotopg = "go to page 3"
then
page = 3 (9 Replies)

of 1-10 with one of 5-20 will result in a combined range of 1-20.
contains ($value)
Returns true if supplied value falls within this range (inclusive). Otherwise returns false.
