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.
