Re : Does sub network assert limits on the remaining address space?

 Hi Shaul Karl,

 it's a long time ago that i read network things to get my modem working,
 what i understand about it, i write to you
 i am nowhere near an expert on this

 i think that hosts on other networks can get netmask of this network
 number of zeros at end of netmask tells them how big network is,
 they assume each network has a network address (ending in all zeros)
   and a broadcast address (ending in all ones)
 
 i dont know how hosts on other network get at this netmask,
   (read libc docs to see if they have a syscall for that)
   i just checked these : you can get 'network part' of an address,
   which tells you size of network, so hosts on other networks can indeed 
     find out netmask.

  they look at netmask, and if that is all they know about that network,
  then they  assume that it has network- and broadcast-adresses

> Would they treat any one of 192.168.*.19[12] in the same way?
 only if its netmask was same

 neither, this is part of Internet Protocol i think, and IPv6 is yet different

 i hope i didnt mislead you more than i helped you,

 you realize that
 external modems are cheaper than winmodems
 when you take into account that
 second hand value of a linux-capable modem is much higher
