How do I specify the IP addresses that can access the SRS?

The Registrar Data Form has a section where you can specify the IP subnets that will be accessing the production SRS. The specified subnets must conform to the following rules:

• A maximum of 2 subnets.
  
  
• A maximum of 64 IP addresses between the two subnets
  
  
• Subnets must be specified in CIDR format (e.g. 192.168.1.0/27) where the "/27" represents the length of the subnet. The limitation on the maximum of 64 IP addresses means that the length will never be less than /26.
  
  
• Examples of valid subnets include:
  
  
• One subnet of 64 hosts (e.g. 192.168.1.0/26)
  
  
• Two subnets of 32 hosts or less (e.g. subnet #1 as 192.168.2.0/27, which represents 32 addresses 192.168.2.0 to 192.168.2.31; and subnet #2 as 192.168.3.0/27, which represents 32 addresses 192.168.3.0 to 192.168.3.31)
  
  
• The specified subnets must fall on valid bit boundaries. For example, a subnet specified as 192.168.2.1/27 is not acceptable because ".1" is not a valid boundary for a /27 subnet. The following table defines the valid boundaries for each subnet length.
  
  

Length of Subnet	Number of Hosts	Boundaries
/26	64	0,64,128,192
/27	32	0,32,64,96,128,160,192,224
/28	16	0,16,32,48,64,80,96,112,128, 144,160,176,192,208,224,240
/29	8	0,8,16,24,32,40,...,248 (in increments of 8)
/30	4	0,4,8,12,16,20,...,252 (in increments of 4)
/31	2	0,2,4,6,8,12,...,254 (in increments of 2)
/32	1	0 through 255 (in increments of 1)
