ICT is hoping to merge some of the subnets that serve Blackett - this gives more flexibility in networking and also means that as machines move around the building they can keep the same IP address. This has been done elsewhere in College without causing any problems but before we make changes I want to make sure that there aren't any IP dependencies I don't know about. The change we want to make is to merge the subnets below: 155.198.200.0/24 - Admin users Levels 1,2,4 and 8 155.198.202.0/24 - Level 3 teaching cluster 155.198.203.0/24 - Level 4 UG labs 155.198.204.0/24 - Astrophysics Level 10/11 155.198.206.0/24 - Levels 0,1,2 155.198.207.0/24 - Laser/Plasma - Levels 6/7 Subnets 201 and 205 are currently not used - these will get added into the pool making more IP addresses available. What I need to know is if anyone is doing anything which depends on them getting (eg) a 206 address down on level 0? Once the subnets are merged no fixed addresses will change but new equipment could get an address anywhere in the range. I'm happy to discuss this with anyone who has any concerns. Steve
