[dns-operations] porttest.dns-oarc.net: check your resolver's source port behavior

[Duane Wessels]

I've put together a quick hack that you can use to check your
resolver's source port characteristics.  Use 'dig' to send a query
to porttest.dns-oarc.net:

    $ dig +short porttest.dns-oarc.net TXT

You should get back some output like this:

    z.y.x.w.v.u.t.s.r.q.p.o.n.m.l.k.j.i.h.g.f.e.d.c.b.a.pt.dns-oarc.net.
    "xxx.xxx.xxx.xxx is FAIR: 26 queries in 0.1 seconds from 25 ports with std dev 3843.00"
