I'm on gprs now and typed ipconfig/all and i see the subnet mask is set to 255.255.255.255.
PPP adapter gprs:
Physical Address.....
DHCP......
IP Address........
Subnet Mask...........255.255.255.255
What does it mean?

IIRC
means your on a class D network
used for the intenet internet
my ip basics rusty bad....
but the netmasq is a way to sub divide ip addresses into networks and then the number of clients/nodes these networks can hold

Those who do not understand UNIX are doomed to reinvent it poorly.
I thought class D wasn't suppose to be in use?
no thats calss E I think

All PPP or PPTP connect's subnet mask is 255.255.255.255 on MS machines, not sure about *NIX. In a PPP or PPTP connect, a subnet mask is not needed.
255.255.255.255 is a broadcast address.

The subnet mask of 255.255.255.255 means that the ip address specified is the only
one in said network. Therefor to reach it additional routes has to be specified.
That type of subnet mask would be used for like a dummy/null interface that routes to
nowhere.
point to point links should have a subnet mask of 255.255.255.252 specifying that there
are only two nodes on that network, your machine and the one you are connected to.
This is all my ccna reading coming out heh
point-to-point and PPP or PPTP are 2 different things. PPP or PPTP does not require a subnet mask.Originally Posted by pogi_2nr
pptp is a vpn protocol?
What do you mean by ppp doesnt require a subnet mask?
If the ppp link is carrying ip packets it requires a subnet mask.
