| Prefix | Specifies the IP address associated with this prefix list. |
| PrefixMaskLen | Specifies the subnet mask length associated with this prefix list. |
| Name | Specifies the name associated with this prefix list. |
| MaskLenFrom | Specifies the lower bound of the mask length. This value, when combined with the higher bound mask length (MaskLenUpto), specifies a subnet range covered by the prefix list. The default value is the mask length (PrefixMaskLen). |
| MaskLenUpto | Specifies the higher bound of the mask length. This value, when combined with the lower bound mask length (MaskLenFrom), specifies a subnet range covered by the prefix list. Default value is the mask length (PrefixMaskLen). |
