IP over DNS
An IPv4 tunnel that carries IP traffic through DNS queries and answers.
DNS can act as a constrained transport layer when ordinary network access is not available. This exhibit represents the broad technique of wrapping IP traffic in query names and answers.
Tunnelling is dual use. The public museum should explain the concept, impacts, and detection context without publishing operational evasion guidance.
