Archived-At: List-Archive: List-Help: List-Owner: List-Post: List-Subscribe: List-Unsubscribe: Dr. Pan, I am still confused by the presences/need of the CGNAT layer in Starlink, vs your slides saying that it's "one big IPv4 hop" Is that the IPv4 100.x on the outside of the customer's access point? Are they unique within Starlink, or unique to each Landing Station? Gosh, I wish they had just done one of the v4-over-v6 mechanisms. -- ] Never tell me the odds! | ipv6 mesh networks [ ] Michael Richardson, Sandelman Software Works | IoT architect [ ] mcr@sandelman.ca http://www.sandelman.ca/ | ruby on rails [
