OK, I'm going to take it you are a IT person and not define anything.
For this TV I'd just set the IP in the TV (hard assign) since Samsung didn't answer your call for a fix.
As to RELEASE, that's not the job of the TV but the DHCP server. Since power can be cut and no DHCPRELEASE message sent. That's all technical so I'm going with the answer is to assign the IP and be done with it.
So, I got a new Samsung TV last month and hooked it up to my network (Wireless). I have 3 other Samsung TVs also. After a couple weeks, when running a Scan of my Network, I noticed that this new TV was taking over 4 ip addresses on my Network and they were all showing as 'alive'. It turns out that every time I power up this TV, it takes a new ip address, but does not release the old ip address. My other TVs don't do this. I am guessing that this is not beneficial to my network. Does someone here understand what is going on here? I have already called Samsung tech support and searched the Internet and came up empty.
