Thanks for all your help. | |The MAC address -- ah, ok. So I would have to replace the |network card like you said. Someone else mentioned that |earlier, too. Now it makes sense. So if I had an extra network |card, switching out network cards would work, but only once |since both network cards would keep their ip addresses for the |terms of the leases. | |Now that I understand, this means that after the term of the |lease my ip address will be up for grabs and there's a chance |that I could get it or someone else could it back, since the |ip address that is on stored in the ip table(s) is not the one |that is actually associated with the mac address in my network |card. When it's lease runs out, the dhcp server will see that |it's not being used and might give it to someone else. Correct. |Actually, unless there's something else to all this, I will |almost certainly lose it, because my network card isn't using |dhcp anymore. So how would it get renewed? It wouldn't, right? Right |It will remain on my system, since I entered it manually, but |the dhcp server wouldn't renew it, because my network card |isn't using dhcp anymore. So if it *happened* to be reassigned |to someone else, there would be a conflict. If wasn't |reassigned, by chance, my connection would continue to work as |long as that ip was never assigned. But someday it would be, |so it would just be a matter of time until my connection would |no longer work, because it would never be renewed via dhcp, |since my network card isn't using dhcp now. Right | |Sighs... so I'd have to check back periodically, by using "host <ip |number>" to see if I still have the lease. When I don't, then I would |number>need |to turned dhcp back on my network card. Does that sound right, |or is there an easier way? Everything depends upon whether or not the sysadmin's are willing to talk to you. They could "reserve" and IP for you from the pool. They could also allocate an IP (or range of IP's) for your machine(s). If you are not on speaking terms with them, then things get harder. Normally though admins reserve a range of IP's for servers. If you know that there are no servers at a particular "reserved" address, use it! Sooner or later they might complain, but when they do you'll know it's time to change your IP... You'll be putting the onus on them... Heh. |Maybe I should try and swap out a |network card from another computer laying around, and get that |one going with dhcp, and then just leave everything alone? | If the sysadmins are uncooperative, that's what I'd do. -JMS
