Re: net mask



hi,
the address your supplied is a C-class address.
This needs netmaks 255.255.255.0
However, the -15 you put behind it is unclear to me, I never have seen that after a ip-number.
Anyways:
A-class 1.x.x.x-127.x.x.x netmaks 255.0.0.0
B-class 128.x.x.x-191.x.x.x 55.255.0.0
C-class 192.x.x.x-223.x.x.x 255.255.255.0
The remaining part os D-class and used for multicasting apart from the 255.x.x.x which is tbe broadcast range.

Netmasks geiven her are ofcourse the most general options and can be different if a ip-blok is subnetted.

Andor
191.x.x.x 55.255.0.0
C-class 192.x.x.x-223.x.x.x 255.255.255.0
