Mostly because DHCP isn't really that simple. It requires you to be able to send and receive packets without having an address of your own, which is kind of a hack around some basic concepts of IP. In other systems, I've implemented other kinds of work-arounds that I think are more aesthetically pleasant, but they're still hacks to an IP purist. Also, I'll bet you don't understand the security and privacy implications described by that passage. In my opinion, they affect very few people. [For example, if someone has physical access to reboot the machine from a floppy, the "security" implications of BPF are irrelevant.] > Then I ran Linux for at least a month.

Use a domain name. If your ISP isn't keeping your DNS name stable, that's a separate problem, but IP addresses aren't *intended* to be human-friendly, and under DHCP, they're not intended to be (dependably) stable, either. > My first question about this is why are these operating systems > different? Unless you've done more configuration of your FreeBSD DHCP configuration, I'd be surprised if they are, in the way you're saying (FreeBSD getting more-stable addresses than Linux). More likely, your ISP has just stabilized their address database in the meantime. > My second, is can I look forward to those weeks (or more) of IP address > stability that I got in NT, even rebooting at least once a day or so? It's unlikely you have any control over this. You can talk to your ISP and ask about setting client identifiers, but if you have a hardware address (e.g., ethernet), that's probably the only clue they use in picking your IP address. It can't hurt to ask, though. The dhcp client does allow you to twiddle any options that the ISP wants. > Ok, and also, the linux netscape seemed much more stable in linux than > the freebsd netscape seems in freebsd.
