IP Multiplex Limit
Does anyone know what the limit is on IP Multiplexing? How many IP's can be assigned to one NIC?
Thanks in advance.

Re: IP Multiplex Limit
256 is the limit of VIPs you can have on on NIC.
I give myself 10 points ;-)

Re: IP Multiplex Limit
Indeed, a "Class-C" network has a single octet of host portion (ie the last 8 bytes) and two of those addresses (0 and 255) are reserved, leaving 254 possible IPs. The number is 256 times that for a "Class-B" and another 256 times that for a "Class-A" address.
Of course, IP addresses have been "classless" for years now, so the more general answer is there are (2^N)-2 host addresses available in a given subnet where N is the number of bits in the host portion of the address.
As one can assign IP addresses from multiple subnets to the same NIC under HP-UX, the "per-subnet" limit to the number of host addresses in an IP subnet is _not_ the limit to the number of IP's one can assign to a NIC.
