OpenDNS Home

Overview

OpenDNS Home is a free DNS service for filtering and basic protection across a household network. It best suits families and technically comfortable users who want one router-level policy for phones, computers, televisions and consoles. The main trade-off is that coverage depends on configuring devices or the home router to use OpenDNS.

Founded in 2006 and acquired by Cisco in 2015, OpenDNS is intended to make home internet use safer and more reliable. Because the service works at the DNS layer, it can cover varied hardware without installing a separate client on every device, provided that hardware follows the configured DNS settings.

Key features

Network-wide coverage

OpenDNS settings apply to devices connecting through the configured home network. Supported examples include laptops, smartphones, tablets, DVRs, game consoles and TVs, as well as computers, smart devices and servers. Setting up the router is the most practical approach for a mixed-device household: new devices can inherit the network policy instead of requiring individual configuration. A device that bypasses the router's DNS configuration will not receive the same filtering.

Custom filtering and protection

OpenDNS Home combines customizable filtering with basic protection against malicious phishing. Its parental controls are designed for every device in the home, making it more useful than a single-device browser filter when children use several types of screens. This is DNS-layer protection rather than a complete security suite, so readers seeking broader endpoint security should look elsewhere.

Family Shield

OpenDNS Family Shield is the better fit when the priority is a preset adult-content block with minimal administration. It requires no sign-up and comes preconfigured, but gives up the category-level customization that defines OpenDNS Home. OpenDNS Public Service is another free option with basic DNS-layer protection and built-in filtering configurations, aimed at users who want a standard configuration rather than household-specific rules.

Setup, support and APIs

The setup guidance recommends configuring a home router and provides the nameservers 208.67.222.222 and 208.67.220.220. Users can instead configure individual devices, although that is less convenient for a large home. FAQs, community forums, documentation and deployment walkthroughs support the process. API guides are included for users who need programmatic control or integration.

Pricing

OpenDNS Home costs nothing. There is no free trial because the service itself is free, and no paid renewal or seat charge is stated. The free plan includes customizable filtering and basic protection, with network coverage determined by the devices and routers using OpenDNS. Family Shield also costs nothing and includes adult-content blocking without sign-up; its fixed configuration is the price of simplicity. OpenDNS Public Service costs nothing and provides basic DNS-layer protection with built-in filtering configurations.

These plans have no published device quota or query allowance. The practical limit is configuration: the policy applies where OpenDNS DNS settings are in use, not automatically to every connection a household member may use elsewhere.

Platforms

OpenDNS supports Android, iOS, Linux, macOS, Windows and the web. Its deployment model also covers home routers, computers and laptops, smart devices and servers, so it can protect equipment that does not support a conventional app.

Who it's for

Choose OpenDNS Home for a household that needs customizable controls across many device types and is willing to change router or DNS settings. Family Shield is more appropriate when adult-content blocking is enough and no account is desired. It is less suitable for users who want per-device controls without network configuration, protection that follows a device onto other networks, or a full endpoint-security package.

Pros and cons

Pros

• Network-wide reach: one router configuration can cover phones, computers, consoles, TVs and other household devices.
• Customizable controls: OpenDNS Home offers more policy control than the preset Family Shield option.
• Free plans: Home, Family Shield and Public Service each cost nothing.
• Phishing protection: malicious-phishing protection adds a basic security layer to filtering.
• Broad deployment support: DNS configuration works with routers, smart devices and servers, not only app-capable hardware.

Cons

• DNS setup required: users must configure a router or individual devices, which is less convenient than an install-and-sign-in service.
• Coverage follows the network: devices using another DNS path or another network are outside the configured home policy.
• Basic protection scope: the service is focused on DNS filtering and phishing protection rather than comprehensive device security.
• Family Shield is limited: its no-sign-up convenience comes with preconfigured blocking instead of customizable rules.

Verdict

OpenDNS Home is a strong fit for households that want free, customizable, router-level filtering across a wide mix of devices. Its decisive advantage is broad network coverage without per-device software; look elsewhere if you need protection that travels with devices, richer endpoint security, or controls that require no DNS configuration.
