Contract # GS00T01AHD0002 

Proposal to Add Federal Telecommunications Service   Long Distance (FTS LD) 

(ARIN). These criteria have been developed to conserve the scarce IPv4 address 

space. The Government will be assigned address space based on the Government's 

immediate need, and future projected needs. Fees may apply based on the number of 

requested and utilized IP Address spaces per rack. 

All address space given out by AT&T is NON PORTABLE   the addresses do not 

belong to the Government and upon cancellation of AT&T service cannot be taken to 

another service provider.  

The ARIN will charge a recurring yearly fee for any address space obtained directly 

from them by the Government or the Government's company. AT&T will not pay 

this fee if the Government obtains address space directly from the ARIN.  

6.7.18  Reaching Peak Performance with Location  

As a compliment to the AT&T Enterprise Hosting Services, our Internet Data Centers 

are optimized specifically to provide an industry leading web, data, and applications 

server hosting environment. Each Internet Data Center is protected from intrusion and 

failure by multi layered security, failsafe redundancy, diversity measures, and rapid 

response recovery measures. 

6.7.19  Internet Data Centers 

As of June 2001, AT&T has 18 operational centers on three continents representing 

1.8 million square feet of web hosting space. Our center locations have been hand 

selected to ensure the greatest diversity across the entire AT&T network thus helping 

increase reach and performance. We are also aggressively expanding our Internet 

Data Center locations. During 2000, we expanded our web hosting floor space by 

more than 600 percent and quadrupled the capacity of our IP backbone.
