Characterizing the use of 10-space within Chemistry and Physics.

Used primarily for two reasons

1. Easy, powerful protection

Easy protection for devices not needing a public IP but benefiting from being on Cornell's network.

Simpler and more bomb-proof network protection than a firewall.

On occasion the device may need a public IP temporarily. Such a change requires modifying the DNSDB record.

This is usually simpler and faster than making changes to CU's ACLs or firewall services.

Use cases in Chemistry

All networked printers.
Many, many computers hooked up to instrument systems.

Magnitude of use

87 On research networks

2. Optimizes use of limited IP space

Affords twice the number of IPs on a network than if 10-space numbers were converted to public IP addresses and blocked at the network layer via firewall.
