* `-http-addr=<addr>` - Address of the Consul agent with the port. This can be
  an IP address or DNS address, but it must include the port. This can also be
  specified via the CONSUL_HTTP_ADDR environment variable. The default value is
  127.0.0.1:8500.

* `-datacenter=<name>` -  Name of the datacenter to query. If unspecified, the
  query will default to the datacenter of the Consul agent at the HTTP address.

* `-token=<value>` - ACL token to use in the request. This can also be specified
  via the `CONSUL_HTTP_TOKEN` environment variable. If unspecified, the query
  will default to the token of the Consul agent at the HTTP address.

* `-stale` - Permit any Consul server (non-leader) to respond to this request.
  This allows for lower latency and higher throughput, but can result in stale
  data. This option has no effect on non-read operations. The default value is
  false.
