  - getAllowLoopback
```
public boolean getAllowLoopback()
```
    Is the bookie allowed to use a loopback interface as its primary interface(i.e. the interface it uses to establish its identity)? By default, loopback interfaces are not allowed as the primary interface. Using a loopback interface as the primary interface usually indicates a configuration error. For example, its fairly common in some VPS setups to not configure a hostname, or to have the hostname resolve to 127.0.0.1. If this is the case, then all bookies in the cluster will establish their identities as 127.0.0.1:3181, and only one will be able to join the cluster. For VPSs configured like this, you should explicitly set the listening interface.
