{
  "[Evaluate](#cfn-ses-mailmanagerruleset-ruleipexpression-evaluate)" : {{RuleIpToEvaluate}},
  "[Operator](#cfn-ses-mailmanagerruleset-ruleipexpression-operator)" : {{String}},

}
```

### YAML
<a name="aws-properties-ses-mailmanagerruleset-ruleipexpression-syntax.yaml"></a>

```
  [Evaluate](#cfn-ses-mailmanagerruleset-ruleipexpression-evaluate): {{
    RuleIpToEvaluate}}
  [Operator](#cfn-ses-mailmanagerruleset-ruleipexpression-operator): {{String}}
  [Values](#cfn-ses-mailmanagerruleset-ruleipexpression-values): {{
    - String}}
```

## Properties
<a name="aws-properties-ses-mailmanagerruleset-ruleipexpression-properties"></a>

`Evaluate`  <a name="cfn-ses-mailmanagerruleset-ruleipexpression-evaluate"></a>
The IP address to evaluate in this condition.  
*Required*: Yes  
*Type*: [RuleIpToEvaluate](aws-properties-ses-mailmanagerruleset-ruleiptoevaluate.md)  
*Update requires*: [No interruption](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/using-cfn-updating-stacks-update-behaviors.html#update-no-interrupt)

`Operator`  <a name="cfn-ses-mailmanagerruleset-ruleipexpression-operator"></a>
The operator to evaluate the IP address.  
*Required*: Yes  
*Type*: String  
*Allowed values*: `CIDR_MATCHES | NOT_CIDR_MATCHES`  
*Update requires*: [No interruption](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/using-cfn-updating-stacks-update-behaviors.html#update-no-interrupt)

`Values`  <a name="cfn-ses-mailmanagerruleset-ruleipexpression-values"></a>
The IP CIDR blocks in format "x.y.z.w/n" (eg 10.0.0.0/8) to match with the email's IP address. For the operator CIDR\_MATCHES, if multiple values are given, they are evaluated as an OR. That is, if the IP address is contained within any of the given CIDR ranges, the condition is deemed to match. For NOT\_CIDR\_MATCHES, if multiple CIDR ranges are given, the condition is deemed to match if the IP address is not contained in any of the given CIDR ranges.  
*Required*: Yes
