-DNS-over-QUIC is a DNS protocol that uses the QUIC transport layer protocol to transmit DNS requests. It solves one of the main problems with the DoH protocol: instability due to head-of-line blocking.
+DNS-over-QUIC is a DNS protocol that uses the QUIC transport layer protocol to transmit DNS requests. It solves one of the main problems with the DoH protocol: head-of-line blocking.
 
 Since DoQ uses the QUIC protocol to keep DNS activity separate from web traffic, it avoids the timing issues observed in DoH. Consequently, it doesn't reveal any traffic patterns. This makes it harder to link your DNS queries to your browsing activity, even though the traffic itself is easier to spot.
 
-If you're looking for a combination of privacy and stability, DoQ is usually the best choice.
+However, DoQ remains an experimental protocol and might face stability problems or be blocked by ISPs and censors. If you are not ready to deal with that, it might not be the best choice.

 Besides plain DNS (both IPv4 and IPv6) AdGuard DNS supports various encrypted protocols, so you can choose the one that suits you best.
 
+### DNSCrypt

+AdGuard DNS allows you to use a specific encrypted protocol — DNSCrypt. Thanks to it, all DNS requests are being encrypted, which protects you from possible request interception and subsequent eavesdropping and/or alteration.

 ### DNS-over-HTTPS (DoH) and DNS-over-TLS (DoT)
 
 DoH and DoT are modern secure DNS protocols that gain more and more popularity and will become the industry standards for the foreseeable future. Both are more reliable than DNSCrypt and both are supported by AdGuard DNS.
