- Splitting subnet masks on a host is often troublesome. We used to run that
- way here at the BEVALAC but it required hacked kernel software to get it
- right. There is usually only one variable for the netmask, not one per
- interface. Even if there is one per interface there are some subtle problems
- that the code must handle correctly for broadcasts, etc., to work all the
- time.
-
- Our solution was to move to a net that had more subnets available so we
- no longer have to split.
