I noticed there is a i.p address in /etc/hosts for my Firestick along, with the virtual wl ssid.

root@DD-WRT:/etc# cat hosts
127.0.0.1 localhost
192.168.1.9 DD-WRT
192.168.3.4 FireStickVWL1.1

I have not edited the hosts file to include Firestick. Is this normal behavior resulting from the the creation of a virtual wl OR is this something that should be a security concern?

A vlan was created to isolate all our tv stuff and it connects through a smart switch. The FireStickVWL1.1 was created to keep it on that isolated vlan. There are no connection issues, but the fact I see this entry in the host file caused concern..

Thanks for the previous help with DoT and Samba.

That file occupies space in RAM and is written to by the system. It is actually part of /tmp.

So this is normal behavior of the kernel to append a new vwl iface to the host file. I would of expected the main wl iface to be appended as well.

will go create a 2nd vwl iface on other vlan to see if it ends up in host file as well...

thanks for the reply D.G

Did you create the static lease in the UI in the Services/Services tab?

Devices added that way end up in the host file

Yes - .... thanks for the explanation..

I was doing something else when I noticed the entry and since it was a new device I added "not to mention it took a long time to ship out of the u.s and the amazon seal tape was re-sealed with clear tape... anyways the entry raised an eyebrow and I thought it would be easier to just ask then go down another rabbit hole..

If your not somewhat paranoid, then you not up on current events.
