Appliances replace DNS, DHCP software

By Carolyn Duffy Marsan

In 2004, the Slammer virus took the city of Houston by storm.
The powerful, fast-spreading virus penetrated the Red Hat Linux
servers running Berkeley Internet Name Domain software that
handled naming resolution for the city's Web sites. The airport
system, public library and health department were among the many
city agencies whose Web sites suffered outages as a result of
the virus.

"The Slammer virus affected all the naming resolution pieces in
the city," says Mark Whitt, IS administrator for the city's IT
department. "We couldn't get the vulnerability under control. So
we began looking for a device to reduce our vulnerabilities.''

Enter Infoblox, one of several start-ups offering
special-purpose, hardened appliances that handle resolution for
key Internet protocols including DNS and DHCP. The city of
Houston bought eight Infoblox appliances - which cost $54,000 -
that will be fully deployed this summer.

"All of our Web presence is using DNS services from Infoblox.
We're also using Infoblox for our internal name resolution,''
Whitt says. "The performance has been great. I haven't seen any
degradation, and we have the enhancements of increased
manageability and dynamic DNS updates.''

The city of Houston is not alone. Many organizations are
replacing aging DNS software and servers with modern appliances
that offer enhanced security and easier management. Other
organizations that have made the switch to DNS and DHCP
appliances include EMC, Banker's Life and Casualty, and Pima
Community College.
