My Samsung UE49KU6400 is using Host Name: localhost, although in Network / Device Name is set as "Samsung 6 Series".
Why is it using the reserved name "localhost"? Doesn't Samsung know that it is not allowed to do that!
"localhost" is meant to be used only for the loopback interface!!!
There is a workaround. the problem is the device name is not hostname compliant out of the box. To be a valid hostname you need to change the device name to only alphanumeric characters: a-z, 0-9. With no spaces. The default device name usually comes with both brackets "" and spaces which throw it off.
Just confirming that the above suggestion (changing the name in TV) worked for me..
Noting that after changing the name to no spaces or round brackets, the TV still displayed '[TV]' in front of the name, but the router now started showing the custom name (without the '[TV]' prefix) versus 'localhost'
Samsung know about this "bug", however are "unable to rectify it at this time", which in in reality is just an excuse to hide how much they make by selling usage of this to 3rd parties including but not limited to, law enforcement, it is a common law enforcement backdoor into most home/small networks/homegroups/workgroups etc and often does not violate your privacy rights due to the broadcast by the tv itself due to samsung
What's the difference between a bug and a glitch? At the end of the day it's an undesired side-effect.
What details do you have about this "glitch" and how does it have anything to do with the device using localhost as it's network hostname?
And how does it make "your entire network insecure"?
This suggestion did not work for me. I have one Samsung TV about 7 years old and another about 5 years old. They either display "local host" as the device name or display no device name on my router's network.
