Preseeded Allocation Types:
Customer netblock (default)	A direct allocation /30 or larger to a customer. Note that this does NOT include RADIUS-routed "netblocks". Non-customer systems should use the "End-use netblock" type.
Static IP - Server pool	A single IP from a pool designated for servers
Static IP - Cable	A single IP address from a designated pool on the cable network.
Static IP - DSL	A single IP address from a designated pool on the DSL network.
Static IP - Dialup	A single IP address from a designated pool on a dialup RAS.
Static IP - Wireless	A single IP address from a designated pool on a wireless connection.
Static pool - Servers	A pool of IP addresses available for one-by-one assignment to servers in a POP.
Static pool - Cable	A pool of IP addresses available for one-by-one assignment to customers on cable.
Static pool - DSL	A pool of IP addresses available for one-by-one assignment to customers on DSL. Individual IPs will be "assigned" to the customer's city, but the pool will remain assigned to its nominal origin.
Static pool - Dialup	A pool of IP addresses available for one-by-one assignment to dialup customers.
Static pool - Wireless	A pool of IP addresses available for one-by-one assignment to customers on a wireless connection.
End-use netblock	A /30 or larger allocation for arbitrary services - note this should not be used for customer connections. Use this if exact tracking of IP usage in the block is not required.
Dialup netblock	Netblock assigned to one or more RAS units in a POP
Dynamic DSL block	Netblock for (mostly residential) PPPoE DSL.
Dynamic cable block	Netblock for (mostly residential) DHCP cable.
Dynamic WiFi block	Netblock for (mostly residential) (mostly) PPPoE wireless.
Dynamic VoIP block	Netblock for DHCP-assigned VoIP services.
Static IP - LAN/POP	A single IP address from a designated pool for internal LANs - either at a single POP or for a VPN.
Static IP - Managment	A single IP address from a designated pool for managed devices.
Static IP - Wifi CPE	A single IP address from a designated pool for wireless CPE devices.
Static pool - LAN/POP	A pool of IP addresses available for one-by-one assignment to internal LAN systems or VPNs.
Static Pool - Managment	A pool of IP addresses available for assignment to managed devices.
Static pool - Wifi CPE	A pool of IP addresses available for assignment to wireless CPE devices.
Reserve for WAN blocks	Reserve a chunk of IP space for core routers/etc.
Reserve for dynamic-route DSL netblocks	Reserve a chunk of IP space for netblocks configured on the customer end via PPPoE/RADIUS. Note that this is similar to the static DSL pool, but IP space is to be allocated as /30 and larger netblocks, not single static IPs.
Reserve for ATM	Reserve a chunk of IP space for allocation to customers on ATM.
Reserve for fibre	Reserve a chunk of IP space for customers on a fibre connection.
WAN block	Individual netblock assignment for a core router. Always taken from a block which has previously been reserved for such assignments.
Dynamic-route DSL netblock	Customer assignment for a netblock configured on the customer end via PPPoE/RADIUS. Always taken from a block which has previously been reserved for such assignments.
ATM block	Customer assignment for a customer on ATM. Always taken from a block which has previously been reserved for such assignments.
Fibre	Customer assignment for a customer on fibre. Always taken from a block which has previously been reserved for such assignments.
Routing	Blocks not actually assigned to a service on their own, but which have been routed to individual POPs- typically /24, /23, /22
Master block	Allocations provided by the regional registry (ARIN, RIPE, LACNIC, AfriNIC, or APNIC)
