This section captures the common validation rules for the IPRange data. The rest of the section assumes the IPRange to be validated is passed as a parameter with the name Param_range.
The following validations MUST pass for Param_range to be valid.
The Param_range MUST a valid IPv4Range or IPv6Range data.
The following fields are mandatory and MUST be specified and valid.
PrefixLength MUST NOT be 0.
StartIPAddress, EndIPAddress, SubnetId MUST NOT be null.
AddressAssignment MUST NOT be None.
CustomFieldValues MUST have the mandatory custom field values having the following ParentCustomFieldRecordId.
Store the CustomFieldValue having ParentCustomFieldRecordId as ManagedByCustomFieldRecordId to ManagedByCustomFieldValue.
Store the CustomFieldValue having ParentCustomFieldRecordId as ManagedByEntityCustomFieldRecordId to ManagedByEntityCustomFieldValue.
If ManagedByCustomFieldValue.BuiltInCustomFieldValueId is BuiltInManagedByValues.MSDHCP, the following checks MUST succeed.
ScopeRecordId MUST be specified and it MUST be nonzero.
DhcpServerName MUST be the same value as ManagedByEntityCustomFieldValue.Value.
UtilizationType MUST be IPUtilizationCalculationType.Auto.
If ManagedByCustomFieldValue.BuiltInCustomFieldValueId is not BuiltInManagedByValues.MSDHCP, the following checks MUST succeed.
DhcpScopeName, DhcpServerGuid and ScopeRecordId MUST NOT be specified.
Performing bitwise AND operation between SubnetId and SubnetMask MUST yield the SubnetId itself.
StartIPAddress MUST NOT be greater than EndIPAddress.
Compute MinimumPossibleIPAddress to be the SubnetId itself.
Compute MaximumPossibleIPAddress by performing bitwise OR operation of SubnetId and SubnetMask.
StartIPAddress and EndIPAddress MUST be within the range of MinimumPossibleIPAddress and MaximumPossibleIPAddress.
If the UtilizationCalculationType is IPUtilizationCalculationType.Static, the UtilizationStatistics MUST be specified.
Initialize ComputedAddressCategory to be AddressCategory.None.
If the Param_range is IPv4Range, calculate ComputedAddressCategory as given below:
If the StartIPAddress and EndIPAddress fall within the public address space as described in [IANA-IPV4] , ComputedAddressCategory is set to AddressCategory.Public.
If the StartIPAddress and EndIPAddress fall within the private address space as described in [RFC1918], ComputedAddressCategory is set to AddressCategory.Private.
If the Param_range is IPv6Range, calculate ComputedAddressCategory to be AddressCategory.GlobalIPv6Unicast if the range falls within the global unicast range as described in [RFC4291].
The ComputedAddressCategory MUST NOT be AddressCategory.None and the ComputedAddressCategory MUST be the same as the AddressCategory in Param_range.
