DNS over HTTPS is a protocol that encrypts DNS packets in HTTPS queries, allowing for the secure transportation of DNS packets. If DNS packets were able to be separated from HTTP, this would be a security risk as DNS packets could still be stolen. By investigating the size (TCP payload) of DNS and HTTP there is a way to tell the two types of packets apart. We found that DNS packets have a consistent size while HTTP packets vary. This means that packet size can be relied on when trying to tell apart DNS and HTTP packets.
