Subnet functional breakdown

  • 128.187.X.X (public systems)
  • 10.1.X.X (IP telephone subnet)
  • 10.2.X.X (student computers)
  • 10.4.X.X (wireless/public wired)
  • 10.5.X.X (campus personnel - faculty, staff, department)
  • 10.8.X.X (special systems - College private servers, super computers)

Clyde Building CAEDM DNS/LDAP = 128.187.56.2
Crabtree Building CAEDM DNS/LDAP = 128.187.48.2

Helper addresses

  • 10.8.125.2 (CTB)
  • 10.8.120.130 (CB)

Most new subnets are 256 addresses in size. That means:

  • Available addresses = 248
  • Router = X.X.X.1
  • Subnet mask = 255.255.255.0
  • Reserved addresses = X.X.X.254-254
  • Broadcast address = X.X.X.255

All subnets will be behind the transparent web proxy servers
