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?

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. - Brian Kantor Network 44 Manager
I remember 44/8 being used at trade shows years ago. As an exhibitor, I brought the misuse to the attention of the show network folks and didn't see it at future shows.
