chrisruffalo/gudgeon: A DNS proxy with blocklists and user/machine groups https://github.com/chrisruffalo/gudgeon

Mon Apr 20 10:32:17 2020

Gudgeon is a caching/blocking DNS proxy server. What sets Gudgeon apart is the ability to segregate machines, subnets, and IP ranges into different groups that all receive different blocking rules. The motivation for Gudgeon comes from the proliferation of devices on my home network that belong either to outside entities (Google, AT&T, Amazon), kids, or unwise adults. Different groups, classes of user, and devices need different blocking rules.

Take, for example, a user who has shown persistent inability to avoid internet scams. You can assign that user's machine(s) to group(s) that block more suspicious DNS requests. On the other hand you might want to allow a device like a Google Home or Alexa unit to have full access to the internet except for tracking/advert websites. You might want to create extensive blocklists to protect kids who use the internet from their devices.

For all of these reasons Gudgeon has been created to allow more flexibility in host-based DNS blocking.

Si tu as un nom de domaine chez gandi, tu peux passer par cela:

https://github.com/lembregtse/gandi-dyndns

un script python qui va mettre à jour ta zone DNS pour prendre en compte la nouvelle IP.

Par contre Attention, les serveurs DNS ont en général un cache des domaines.
donc ton site risque d'être inaccessible quelques heures / minutes après un changement d'IP.
