Is it safe to change the DNS on a receiver?

Changing a network setting is a fair thing to be cautious about. Here is what a DNS change really does — and what it does not.

What DNS is

DNS is the phone book of the internet: it turns a name like vtuner.com into a numeric address. When your receiver looks up the (now-defunct) radio directory, it asks a DNS server for that address. Point it at Retune·FM and the lookup returns a working directory instead of nothing.

Only the radio directory is redirected

Retune·FM’s DNS answers only for the legacy radio-directory domains (vtuner.com, radiodenon.com, radiomarantz.com and a couple of others). Every other lookup is forwarded to public resolvers unchanged. It does not sit between you and your bank, your e-mail, or anything else, and it cannot read traffic to sites it doesn’t host.

Nothing is logged, and it’s reversible

DNS query logging is switched off — the resolver does not record which names are looked up or from which address. And the change is completely reversible: set the receiver’s DNS back to Automatic and everything is exactly as before. Nothing is installed on the device.

The safest way to apply it

Set the DNS on the receiver itself, not on your whole router. Then only the receiver is affected and every phone and computer keeps its normal DNS. Full detail is on the DNS privacy & security page.
