We tend to try stick with the various TEST-NET CIDRs etc as well in
Designate, and document them here:

When I handle some stuff related to Manila recently, I found a case
which may be suitable for Oslo, Anyhow I put it in the maillist so it
can be discussed before I put it in action.
In testcase, we need a function(maybe 2) to generate random ip address
(or network), also they should in the range of [1](ipv4 documentation
range) or [2](ipv6 documentation range), this is the draft code for ipv4:
import six
import random
def rand_ipv4(network=False):
"""This uses the TEST-NET-3 range of reserved IP addresses."""
test_net_3 = '203.0.113.'
if network:
host_length = random.randint(0, 8)
address_segment = random.randint(0, 8 - host_length)
address_segment <<= host_length
address = test_net_3 + six.text_type(address_segment)
address = '/'.join((address,
six.text_type(32 - host_length)))
else:
address = test_net_3 + six.text_type(random.randint(0, 255))
return address
The primary use case here is writing testcases, I am not sure whether
it is suitable here, or maybe I misunderstood the intention of
TEST-NET-3, please leave any comment you like.
