I'm coding a network program and i need it to "understand" ip ranges, but i don't know how to make to parse an IP CIDR range, let's say "172.16.10.0/24" to work with the specified IP range.
I've found a program which does it, but i don't understand the code. Here is the function:
So, please, can somebody explain me how to do this or at least, what does this function do?
Hi
I have a CSV file with me in this format
Currency, USD, EUR,
USD, 1.00, 1.32,
EUR, 0.66, 1.00,
How do I transpose the file to get to the format below.
currency, currency, rate
USD, USD, 1.00
USD, EUR, 1.32
EUR, USD, 0.66
EUR, EUR, 1.00
Thanks for your help

Hi all, I would appreciate if someone could share how to convert CIDR notation to netmask and vice versa.
The value below is just an example. it could be different numbers/ip addresses.

netmasks
netmasks(4) File Formats netmasks(4)NAME
netmasks - network mask database
SYNOPSIS
/etc/inet/netmasks
/etc/netmasks
DESCRIPTION
The netmasks file contains network masks used to implement IP subnetting. It supports both standard subnetting as specified in RFC-950 and
variable length subnetting as specified in RFC-1519. When using standard subnetting there should be a single line for each network that is
subnetted in this file with the network number, any number of SPACE or TAB characters, and the network mask to use on that network. Network
numbers and masks may be specified in the conventional IP `.' (dot) notation (like IP host addresses, but with zeroes for the host part).
For example,
128.32.0.0 255.255.255.0
can be used to specify that the Class B network 128.32.0.0 should have eight bits of subnet field and eight bits of host field, in addition
to the standard sixteen bits in the network field.
When using variable length subnetting, the format is identical. However, there should be a line for each subnet with the first field being
the subnet and the second field being the netmask that applies to that subnet. The users of the database, such as ifconfig(1M), perform a
lookup to find the longest possible matching mask. It is possible to combine the RFC-950 and RFC-1519 form of subnet masks in the net-
masks file. For example,
128.32.0.0 255.255.255.0
128.32.27.0 255.255.255.240
128.32.27.16 255.255.255.240
128.32.27.32 255.255.255.240
128.32.27.48 255.255.255.240
128.32.27.64 255.255.255.240
128.32.27.80 255.255.255.240
128.32.27.96 255.255.255.240
128.32.27.112 255.255.255.240
128.32.27.128 255.255.255.240
128.32.27.144 255.255.255.240
128.32.27.160 255.255.255.240
128.32.27.176 255.255.255.240
128.32.27.192 255.255.255.240
128.32.27.208 255.255.255.240
128.32.27.224 255.255.255.240
128.32.27.240 255.255.255.240
128.32.64.0 255.255.255.192
can be used to specify different netmasks in different parts of the 128.32.0.0 Class B network number. Addresses 128.32.27.0 through
128.32.27.255 have a subnet mask with 28 bits in the combined network and subnet fields (often referred to as the subnet field) and 4 bits
in the host field. Furthermore, addresses 128.32.64.0 through 128.32.64.63 have a 26 bits in the subnet field. Finally, all other
addresses in the range 128.32.0.0 through 128.32.255.255 have a 24 bit subnet field.
Invalid entries are ignored.
