The Teredo Bubble Packet primarily ensures what?

The Teredo Bubble Packet primarily ensures what?

• A. It performs address resolution
• B. NAT mapping remains active
• C. It ensures quickest data transfer
• D. It resolves hostnames

Answer: (B)

The main idea is that Teredo Bubble Packets serve as keep-alive messages to keep NAT mappings active for the Teredo tunnel. Teredo carries IPv6 over UDP over IPv4, and NAT devices typically drop or time out mappings that don’t see traffic. The bubble is a small, periodic UDP packet sent through the Teredo path to refresh the NAT translation, preventing the mapping from expiring so IPv6 traffic can flow when needed. It isnures the NAT binding remains open, allowing the Teredo tunnel to function smoothly. It’s not about resolving addresses, speeding up data transfer, or resolving hostnames.
