  Every Web session involves a DNS resolution. While, in the last decade, we
witnessed a promising trend towards an encrypted Web in general, DNS encryption
has only recently gained traction with the standardisation of DNS over TLS
(DoT) and DNS over HTTPS (DoH). Meanwhile, the rapid rise of QUIC deployment
has now opened up an exciting opportunity to utilise the same protocol to not
only encrypt Web communications, but also DNS. In this paper, we evaluate this
benefit of using QUIC to coalesce name resolution via DNS over QUIC (DoQ), and
Web content delivery via HTTP/3 (H3) with 0-RTT. We compare this scenario using
several possible combinations where H3 is used in conjunction with DoH and DoQ,
as well as the unencrypted DNS over UDP (DoUDP). We observe, that when using H3
1-RTT, page load times with DoH can get inflated by $>$30\% over fixed-line and
by $>$50\% over mobile when compared to unencrypted DNS with DoUDP. However,
this cost of encryption can be drastically reduced when encrypted connections
are coalesced (DoQ + H3 0-RTT), thereby reducing the page load times by 1/3
over fixed-line and 1/2 over mobile, overall making connection coalescing with
QUIC the best option for encrypted communication on the Internet.
