Control D

DNS filtering and traffic redirection platform for profiles, devices, custom rules, folders, schedules, and analytics.

Helps network operators that build DNS rules into profiles and folders, enforce profiles on devices, schedule policy windows, and view query analytics.

Example Use Cases

These are example ways Snow can use Control D when building apps with you. This list is meant to show examples, not document every possible capability. Connecting an account does not make Snow run these automatically on its own.

Bulk Update Profile Filters

Tool to bulk update filters on a specific profile. Use when you need to enable or disable multiple filters at once. Provide a list of filter IDs with desired states.

Create Custom DNS Rule

Create custom DNS rules for a profile to control domain resolution. Use this to block ads/trackers, bypass filtering for specific domains, spoof DNS responses with custom IPs, or redirect traffic through proxies.

Create Custom Rules in Profile Folder

Tool to create custom rules within a specific folder for a profile. Use after confirming the profile and folder IDs and preparing rule definitions.

Create Device

Create a new device (DNS endpoint) in Control D. Each device gets unique DNS resolvers that enforce configured profiles. Requires a valid profile_id from GET_PROFILES. Returns DNS resolver URLs (DoH, DoT) and IPs for configuring client devices.

Create Profile

Create a new blank profile or clone an existing one. Profiles define DNS filtering rules, services, and settings that can be applied to devices. Use this to provision a new profile before assigning rules, filters, or devices to it.

Create Profile Schedule

Create a new time-based schedule within a Control D profile. Schedules allow automatic enforcement of profile rules during specified time windows. Use this to set up recurring time periods (e.g., work hours, bedtime) when specific DNS filtering rules should apply. Requires a valid profile_id from GET /profiles.

Delete Device by ID

Permanently delete a Control-D device/endpoint by its ID. WARNING: This is a destructive operation. Deleting a device will break DNS resolution on any physical gadget configured to use this device's unique DNS resolvers. Use GET /devices to retrieve valid device IDs before calling this action.

Delete Profile

Permanently deletes a Control D profile by its unique identifier (PK). IMPORTANT: The profile must be orphaned (not enforced by any device) before it can be deleted. If the profile is currently assigned to one or more devices, the deletion will fail. Use this tool when you need to remove an unused profile from the account. To check if a profile is safe to delete, first verify it has no associated devices using the Get Devices or Get Profile endpoints.

Delete Profile Rule by Rule ID

Delete a custom DNS rule from a Control D profile by its rule identifier (hostname/domain). This tool removes a DNS filtering rule from the specified profile. Rules in Control D are identified by the hostname/domain they target (e.g., 'example.com', 'ads.domain.com'). Prerequisites: - Obtain profile_id from GET /profiles endpoint - Obtain rule_id (the hostname/domain) from GET /profiles/{profile_id}/rules endpoint Note: Requires write access to the API (read-only tokens will receive a 403 error).

Delete Profile Schedule

Tool to delete a specific schedule within a profile. Use after confirming profile_id and schedule_id.
