dnsdist has the concept to "server pools", any number of servers can belong to a group.
+A default pool, identified by the empty string ``''`` is always present, and `newServer` without a pool argument will assign the new server to that pool.
Let's say we know we're getting a whole bunch of traffic for a domain used in DoS attacks, for example 'example.com'.
We can do two things with this kind of traffic.
:class:`Server`\ s can be part of any number of pools.
Pools are automatically created when a server is added to a pool (with :func:`newServer`), or can be manually created with :func:`getPool`.
+Servers that are not assigned to a specific pool get assigned to the default pool that is always present, identified by the empty string ``''``.
