Dear SixXS and deham02 staff, tl;dr requesting a second subnet on T35633 for educational purposes Tunnel ID: T35633 Subnet ID: R15213 NIC Handle: DLP6-SIXXS (OR: DAN1337-RIPE) In refer to: https://www.sixxs.net/faq/connectivity/?faq=onlyonesubnet I am currently working on my bachelor thesis, aimed to deploy IPv6 at my University using a core to edge strategy. To emulate the Campus network (/48) AND access some of the servers and devices in my setup, I am in need for a 'fallback network'. This is due to a few restrictions regarding the laboratory setup. I'd like to request a 2nd subnet on the tunnel mentioned above with a size of /64 or larger. I really know that the /48 I already have is more than enough for nearly all setups I can imagine, but I'd like to be as similar to the future topologie as possible. The easier it is for the involved people to deploy my solution later, the sooner the students will be able to use native IPv6. Please feel free to ask for further information if required. I can also provide a whiteboard picture showing the laboratory setup, but it may hurt your feelings :) Thanks for reading, and big thanks to deham02 and SixXS for providing connectivity. Greetings, Dan Luedtke
