Several NI&S employees have suggested a more accurate motto would read "F*ck you; we turned it off", in reference to several services essential to the jobs of departmental IT, like rdweb, the "temporary" port 22 block, the L2TP VPN, and several other useful services. Unlike most departments, CNS operates as an auxillary service, and therefore recieves funding through cost-recovery rather than university budgets. Individual departments and students must pay a ''per-port'' charge for each IP or phone device attached to the network.

 === IPv6 ===
-CNS is a leader in the transition to IPv6, as their [[w:Autonomous System|ASN]] consistently ranks in the top 5 in terms of percentage of IPv6 traffic, according to [http://www.worldipv6launch.org/measurements/ World IPv6 Launch Measurements]. A dual-stack topology exists for the entirety of campus, but not all systems connected to the network are IPv6-enabled. One system that notably lacks connectivity is the main vt.edu website, which is due to a lack of support from the load balancers currently in use. For legacy reasons, Virginia Tech continues to use its /48 sub-allocation from the [[w:University of Maryland|University of Maryland]], instead of its assigned IPv6 block (2607:b400::/32). It is unknown when the new address space will begin to be used.

 From the Andrews Information Systems Building, there are redundant fiber connections to the main campus at both [[Burruss Hall]] and [[Cassell Colliseum]]. [[Owens Hall]], [[Hillcrest Hall]], and [[Shanks Hall]] have intermediate routers for some buildings. Nearly all ethernet portals on campus are capable of 100 Mbps or Gigabit speeds, due to fiber interconnects between buildings; however, intrabuilding wiring varies in age and may not support high speeds. The vast majority of campus IPv4s come from two directly-allocated blocks (128.173.0.0/16 and 198.82.0.0/16).
