Re: RPG TCP/IP problem

[Philipp Rusch <philipp.rusch@xxxxxxxxxxxx>]

Hello Darren,
your information is simply not sufficient to say yes or no !
Giving an ip address without the subnet mask is like giving the streetname
(a long road assumed) without the number of the house.
So, *if* your network has a subnet-mask in such a way that these addresses
you gave us are both in the same segment, then you don't need to route.
This would normally be the case with an 255.255.255.0 mask (sometimes noted
as /24 = 24 bits mask in so called "Cisco notation")
Since your network doesn't have private addresses, chance are that you have
a different mask, for instance /27 = 255.255.255.224 which would give you a
net with 30 hosts starting from 194.130.10.0 and ending at 194.130.10.32
and a second net from 194.130.10.33 to 194.130.10.64 and so on.

HTH, Philipp

you see the logic behind it ?
Only the "unmasked" bits are used to address the hosts inside your segment.
