Hello, Im trying to monitor & control my dns in my network. I like the idea & features of nextdns but all your traffic goes trough them right? I wanna host something simular. I currently have pi-hole installed but i feel like its not as advanced as something like nextdns. What service could i use for this? Thanks for your time!
all your traffic goes through them right?
Depending on provider and intended purpose… strictly speaking, a DNS server tells your computer that
example.com
resolves to169.254.169.254
and nothing more.However, for example, if your DNS provider adds ad blocking, they may choose to change
ads.example.com
from169.254.169.254
to127.0.0.1
thereby preventing any advertiser JavaScripts from being requested. This is fine and all, but you’d have no way to be automatically alerted if they changed it to123.234.123.234
and serve their own blank scripts.If for example your DNS provider provides region bypass for streaming providers, they could resolve
streaming.example.com
from169.254.169.254
to a server in another country with address123.234.123.234
; and route your request through that in order to circumvent the region lock.These are all fine and well, but if the provider was compromised and/or sold to malicious actor, they could resolve
your-bank.website
to a phishing site, and then MITM all the traffic just like the region lock bypass example.So… in theory, it shouldn’t do anything more than resolving, but in practice, it may be hard to detect, and they could be doing more than just resolving.
