Subject: Questions regarding usage off 44/8 parts outside of ampr.org
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:
https://docs.mesosphere.com/1.10/networking/virtual-networks/ip-per-conta=
iner/
Is this already known?
73,

While I was unaware of DC/OS specifically using this subnet, I do
know that for many years software from various companies have used
parts of network 44 for "internal-only" networking. In particular,
an obsolete document, which is still available via Google searching
refers to 44.128.0.0/16 in terms which seem to have lead these firms
to believe that it is another RFC1918-style "private network" and
they may use it in that way.
Most of these firms seem to be ignorant of the various RFC1918
networks that are intended for this use. Many of them should be
using the link-local addresses of 169.254.0.0/16, but apparently
don't know about them.
When contacted by me about the misuse of network 44, some are
cooperative and some pull up the obsolete document as justification,
while a small number take up a combative stance and tell me to
contact their lawyers.
Just to make it specific: 44.128.0.0/16 is a subnet currently
reserved for testing in the amprnet. It should not be used outside
Amateur Radio.
