If you have an ASN and you take routes from one or more upstreams &/or peers
therefore you do not have a default route in your network
you are part of the DFZ.

Bringing up whether or not people pay for transit or peer all their
traffic off to other big players or mooch free transit from their
friends' companies simply clouds the issue.  The DFZ contains everyone
who gets indigestion from internet routing table growth... from
basement multihomers to major universities to large enterprises to
multinational ISPs.
