With ads found on most websites, smartphone apps, and other digital resources, many look for ways to get rid of ads as they browse the Internet, especially in their home network. In addition to blocking ads, you may want to improve security and block other web resources and sites from your Internet Service Provider. Adguard and Pi-Hole are the most popular DNS sinkholing solutions available. In this post, we will look at several of each solution’s key features and which one you may want to choose between Adguard home vs. Pihole.
DNS Server
DNS servers are important in the communication of network traffic across the Internet. DNS has been described as the phone book for the Internet. Instead of remembering difficult IP addresses, DNS translates friendly names to IP addresses, so we don’t have to remember these numbers.
DNS sinkhole
While it might seem a bit overwhelming, The concept of DNS sinkholing is pretty straight forward, even for non tech savvy users. DNS ad blockers like AdGuard Home Server and Pi-Hole work by intercepting DNS queries on the network level. They use DNS blocker configuration to block ads and other unwanted content, such as malware domains and blocking phishing sites on your computers, phones, mobile, and other devices on the whole network.
By blocking DNS requests to specific domains, these solutions prevent ads from being displayed on web pages and in apps. Clients take advantage of this DNS blocking capability by setting the Default DNS servers of clients to point to the DNS sinkhole solution. These can also perform other services like DHCP settings and other network services for any device connected to the network, such as home assistant.
No block page
The difference with DNS sinkholing is that users don’t get a block-page. It simply prevents elements on a web page from loading. The exception is with Parental control option in Adguard, which displays a block page.

Problems with Pi-Hole
While Pi-Hole is an excellent DNS ad blocker, there are some downsides:
Lack of “officially” supported encryption: Pi-Hole doesn’t natively support DNS over HTTPS or DNS over TLS, which means your DNS queries may not be encrypted by default.
Limited parental control features: Pi-Hole lacks advanced parental control options, like forcing safe search on search engines or blocking adult content.
Resource usage: I have seen reports that Pi-Hole might consume more resources on your device than AdGuard, especially on a Raspberry Pi. However, I have not really tested this for a true comparison.
Clients Configuration
To start using AdGuard or Pi-Hole, you must configure your devices to use them as DNS servers. This can be done on individual devices or at the router level, depending on your network setup.
Router configuration: Update your router’s DNS settings to point to the IP address of your AdGuard or Pi-Hole installation.
Device configuration: If you prefer to configure specific devices, update the DNS settings on each device to use the IP address of your AdGuard Home or Pi-Hole installation.
Lack of “officially” supported encryption
Pi-Hole does not officially support encrypted DNS protocols like DNS over HTTPS or DNS over TLS out-of-the-box. However, it is possible to configure Pi-Hole with additional software, such as a third-party DoH or DoT proxy, to encrypt DNS queries.
Quickly Block Well-Known Services
