J'ai generally seen that DHCP lease times are assez long (a day plus) on le plus defaults. J'ai a client that seems to have le suivant problem. They have a DHCP server in a router that is near-saturation (say in a normal work day 80-85% of le potential IPs are used). Occasionally they redémarrez leir router. When that happens it seems that le the router loses its table of assigned IPs, so it assigns IPs anew (of course).
The problem is that assez often there is a client on le LAN qui has le IP déjà et is going to hold it for a day (the current timeout length), causing an IP conflict et connectivity issues for those two machines.
The obvious solution is to make a très short lease time, mais depuis Je suis seulement a hobbyist quand it comes to networking, there may be more to DHCP that Je ne understand.
Is le ci-dessus a reasonable evaluation of le situation (at least avec lower-end equipment) et does a lower lease time (say a half-hour) make sense dans ce cas?
