Hi, the prefixes in question (144.48.82.0/24 and 185.121.178.0/24) are no longer announced today after forwarding the original email to NetworkSupportEngineers-SoftLayer-WW@wwpdl.vnet.ibm.com and peering@softlayer.com Thanks Best regards Katie Holly On 4/26/19 10:57 PM, Sandra Murphy wrote:

Hi!

I try to keep track of prefix mis-originations that I see announced publicly.

For this one, you did not mention the prefixes involved, so I tried to discover the prefixes you might hold, based only on the info gleaned from your message.

I’ve found a handful of prefixes associated in some way. None of them seem to be originated by AS36351. They are all originated by AS204136.

Would you be willing to confirm whether any of these are the prefixes in question?

185.121.177.0/24 185.121.163.0/24 5.253.85.0/24 103.230.141.0/24

185.140.114.0/24 185.140.115.0/24 169.239.202.0/24

(6 of the 7 are protected by an RPKI ROA, which is good.)

btw. I typed meo.ws into a web browser, expecting only to receive a list web search results, but I found that meo.ws replies - with what looks like a set of info and references you find generally useful.

Hi,

anyone from SoftLayer (AS36351) around or someone with a contact to their NOC? They have been announcing two /24's from us without permission and we'd like them to remove the announcement immediately.

Emails were sent to ipadmin@softlayer.com, abuse@ibm.com and ipreg@us.ibm.com without success hence I'm reaching out to this list as a last resort.

Thanks
