'Google, this is bogus as hell' — one of the fathers of the internet blasts Google for how Chromecast behaves on his home network

"Google, this is bogus as hell," Paul Vixie ranted on Internet Engineering Task Force mail list this week. The IETF mail list is where the people who create the internet's technologies converse.

The post was noticed because Paul Vixie is an Internet Hall of Fame engineer known for his pioneering work on the modern Domain Name Service (DNS).

And it is how Google was using DNS in its Chromecast Ultra streaming device that ticked him off.

[...] [Vixie] bought a Google Chromecast. But when he went to set it up, he found it doing something no device in his network is allowed to do: It wouldn't use his own, private DNS server. It would only use Google's public server.

    > It is absolutely expected that when a device is told to use a given DNS and/or gateway it will use it

    Funny, I don't read the RFC as saying "The client MUST respect any non-IP related configuration pushed via DHCP". All RFCs are carefully worded, and any requirements are explicitly stated with MUST. Just because you or anyone else personally expect it to happen does not mean the standard requires it.

    Also and again, you don't seem to understand. The gateway is a part of IP configuration. DNS is not. DNS is at the application level. This is equivalent to DHCP pushing a configuration saying whether clients should use a light or dark UI theme and the OS and individual applications deciding whether or not to respect that.

    Also and again, you failed to cite the exact RFC passage that states the client MUST use any DNS advertised via DHCP.

    Also and again, you're ignoring the fact that an application is not required to use the OS name resolution. Even if we assume incorrectly that the Chromecast OS MUST use the DNS server provided via DHCP, the Chromecast service running on that device is under no obligation to use the name resolution provided by the OS.
