samsung TV DHCP

[#1]

i have a annoyance   i have found the problem but cannot find how to fix it , My Router logs continuosly gives this error

"dnsmasq-dhcp[22989]: not giving name localhost to the DHCP lease of 192.168.1.112 because the name exists in /etc/hosts with address 127.0.0.1"

The problem acording to Mr Google is my Smart TV Name , i cannot remove the brackets within the TV settings it shows as

[TV]  samsung ,, and cannot remove the braceted TV

I dont think its causing any problems except being a annoyance to myself seeing it fill router log .

I have the ASUS DSL ac68u witth latest firmware , i am only a beginer at networking so if you know the explanation Simple is good

Does the router have an option to 'always assign the same IP address' to the TV? I'm wondering if it helps to assign a static local address via DHCP. If that doesn't help, doe the TV allow you to specify a static local address in the settings menus?

Bit off topic but I have a Samsung Smart TV and I've noticed it making outbound requests to a couple of host names every few minutes that no longer exist in DNS so the lookups fail, eg:

12:35:05, 01 Aug.DNS name resolution failure (sd1pwpki006.centricaplc.com)
12:32:35, 01 Aug.DNS name resolution failure (euontv.internetat.tv)
12:32:35, 01 Aug.DNS name resolution failure (euontv.internetat.tv)
12:27:35, 01 Aug.DNS name resolution failure (euontv.internetat.tv)
12:27:35, 01 Aug.DNS name resolution failure (euontv.internetat.tv)
12:22:35, 01 Aug.DNS name resolution failure (euontv.internetat.tv)
12:22:35, 01 Aug.DNS name resolution failure (euontv.internetat.tv)
12:17:35, 01 Aug.DNS name resolution failure (euontv.internetat.tv)

I contacted Samsung about it a while back but they didn't seem interested and told me to speak to my ISP instead

All sensible hardware has a network name of localhost which it uses to refer to itself.

Unfortunately, this crappy Samsung doesn't know this and asks the router to give a local IP address for localhost. Since the router has already allocated localhost to itself, it knows this is an error.

BTW Those log entries [correction] maybe shouldn't give DNS faults:-

Why? The output from your dig commands showns one of the domains lacking any forward A/CNAME records, whilst the other has a CNAME that points to a non-existent domain?
