@NotNull

```
    Retrieves the set of currently defined system properties. If possible, this will simply return the result of a call to System.getProperties. However, the LDAP SDK is known to be used in environments where a security manager prevents setting system properties, and in that case, calls to System.getProperties will be rejected with a SecurityException because the returned structure is mutable and could be used to alter system property values. In such cases, a new empty Properties object will be created, and may optionally be populated with the values of a specific set of named properties.

    Parameters:
    
    nameResolver - The name resolver to use to obtain the canonical host names. If this is null, then the LDAP SDK's default name resolver will be used.

```
    Retrieves a version of the provided host address with the interface name stripped off. Java sometimes follows an IP address with a percent sign and the interface name. If that interface name is present in the provided host address, then this method will trim it off, leaving just the IP address. If the provided host address does not include the interface name, then the provided address will be returned as-is.
    
    Parameters:
    
    hostAddress - The host address to be trimmed.
    
    Returns:
    
    The provided host address without the interface name.

If this is true, then this method will return true for addresses in a private-use network range; if it is false, then this method will return false for addresses in those ranges. This does not have any effect for addresses in other reserved address ranges.
    
    Returns:
