Pros,
I was wondering if there is a API for generating ip address range from
a given subnet mask (VLSM).
Thanks,

Hi all,
socket.gethostbyname_ex(socket.gethostname()) will return the list of IP
addresses on a the local host. I did not find any function that can be
used to get the subnet mask and default gateway.
Under Win32, the Win32 IP helper API provides a GetIpAddrTable()
function that returns information that contain the subnet mask, but
that's Win32 level, and is not portable. Is there something available
in the Python library for that...

Hi,
This is a C programming specific with TCP/IP relation.
Supposed I have two string (char *) variables with the following assignment:
ip_str = "10.1.2.3"
netmask_str = "255.255.0.0"
How can I use C programming technique to get the subnet 10.1.0.0?
I tried to use "struct in_addr", but not sure how to start writing a

I'm looking for a function to return true/false depending on if two supplied
IP's (as strings) are in the same subnet (also supplied).
Im getting nowhere fast unfortunately - I know the theory behind it, but I
have no idea on how to actually implement it!
I have split my supplied 3 IP's into 4 numbers each, but past that I'm
stuck - on paper I would convert them to binary and write down all the 1's
and 0's then figure it out, but in...

Hmm, this doesn't seem to work. I am probably tackling it completely the
wrong way, but basically I want a function to receive two IP's and a subnet
mask and return True if IP1 and 2 are on the same subnet, otherwise false.
I have got this so far:
Private Function IsSameSubnet(ByVal IPSource As String, ByVal IPDest As
String, ByVal IPSubnet As String) As Boolean

I am using VB 2005. I can't seem to find a way to get my local Subnet Mask.
The only thing mentioned from googling is the GetIpAddrTable API, but so
far, i've had no luck getting a call to it working. Another idea was to
traverse the registry at
HKLM/System/CurrentControlSet/Services/Tcpip/Parameters/Interfaces. But
that seems really sloppy. One would think that VB 2005 would have a
My.Computer.Network.Subnet property.

is a tricky (at least for me) piece of network address logic. I need to

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:

I'm a network technician in training and I need your help.
I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
