Hi.
My company plans to use DC/OS from Mesosphere and DC/OS is using
44.128.0.0/20 per default for overlay networking.
This seems to have no impact since this overlay nets are only used in
DC/OS clusters and not routed to the Internet, but might lead to
problems in some cases...
Their documentation with this informations can be found at:

You're posting using quoted printable, don't do that. I've fixed your link.
Is this already known?
News to me, and a really poor idea. There's other networks which could be used
for this, without stepping on allocated space. 44.128.0.0/20 isn't used now,
but neither was 1/8 or 5/8. I kinda want to announce 44.128.0.0/20 just to
mess with them, might freak out if there's a route to that :)

Yes, one should consider announcing 44.128.0.0/20. They are squatting on
space which is not theirs to squat on.
In addition to announcing 44.128.0.0/20, it may be good to ensure all of
44.0.0.0/8 is visible in the default-free zone and drop any packets
received for unused IP addresses within 44.0.0.0/8 on the floor.
The Internet default-free zone at times seems to adhere to a "use it or
lose it" mantra, and while this is unfortunate; announcing the 44net to
the internet at large will send a clear message that the space is
actually in use and should not be squatted on.
To completely cover the 44net block from a BGP perspective, in addition
to the existing 44.0.0.0/9 and 44.128.0.0/10 announcement, 44.192.0.0/10
should also be announced (and nullrouted) from some vantage point.
I'm happy to do so if the community accepts my help in this regard. I
have facilities to announce the prefix and ignore any traffic received
for it.
Kind regards,

If this is decided to be a good idea, I can help too - I also have facilities and and
submit the routes as a customer route to 3356 and 174 (and 2914 but I expect Job has this
well covered <g>) which might help from a “customer routes” vs. “peer routes”
perspective.

I can also help in this endeavor if required, but I think the /20 should be a bit split
into two parts (2 x /21) for example, just to be more specific (in getting the point
across). :-)

Adam (and others),
Please don't advertise 44.192.0.0/10. To do so would cause some
fairly significant problems. I am preparing a document to explain
what's up with this and hope to have it ready in a week or so.
I ask your patience.

44/8 is by default routed to UCSD, so the /20 part IS already routed.
Announcing the /20 would be useless imo
