If you utilize services of internet giants or content delivery networks, ECS will likely give you [the shortest distance, the lowest latency, the highest speed](https://en.m.wikipedia.org/wiki/Edge_computing) and may help with decreasing your _digital carbon footprint_.

### Is this a relevant question?
|
||||
|

It's likely greener to just use adblocking DNS no matter where it is located,
|
||||
preferably on router level. I don't trust router/DHCP provided DNS and encrypt
|
||||
it on the end device anyway. And if something needs unfiltered access
|
||||
(AdNauseam?), give it DNS over HTTPS like all browsers and curl have the
|
||||
ability nowadays.

- Personal servers: Personal preference, you could even use all of the DNS servers or be your own recursor. I again have small preference towards Quad9 ECS as titlefetching for unencrypted IRC connection is already open for mass surveillance and there is no telling who triggered a DNS query there anyway.
|

- Business/association/enterprise/whatever device: there may be free political/regulational/bureaucratic/whatever brownie points for using DNS0.eu with the queries not being transmitted outside of the EU.
|

|

This may also be a wrong approach entirely and it should just be an adblocking
|
||||
DNS as noted before.
|
||||
|
||||
Additionally DNS filtering for web browsers may be irrelevant if browser
|
||||
policy enforces extensions that block malicious domains (such as µBlock Origin
|
||||
or AdNauseam) or even Google Safe Browsing.
