7. Services, Linknets and Loopbacks
This single /48 provides subnets required on the university backbone network independently of a department or college. The most common example of this is a server network for a central service provider such as OUCS, BSP or NSMS. The network is split into 32 /53 sections, each providing up to 2048 /64 service networks.
In the first /53 section, one /64 subnet will be reserved for providing the loopback addresses used by routing devices on these networks. A further 1023 /64 subnets are available for server networks, and a further 1024 subnets will be available for linknets as explained earlier in this document.
It is likely that the first block of server networks (with more memorable and recognisable numbers) will be reserved until we have a clear picture of the eventual allocation strategy for central services.
