TWC/Charter/Spectrum contact off-list ? (Reverse DNS issue)
by Brandon Applegate 17 Mar '18

17 Mar '18

Hello, I had success with this issue about 2 years ago when some TWC folks contacted me. I don’t know if those folks are still with TWC/Charter here in the end of 2017 - hence posting on NANOG. The tl;dr is IPv6 reverse DNS issues. It was broken, got fixed, and seems to have broken again recently. Thanks in advance. -- Brandon Applegate - CCIE 10273 PGP Key fingerprint: 0641 D285 A36F 533A 73E5 2541 4920 533C C616 703A "For thousands of years men dreamed of pacts with demons.

Finding scale in Columbus, OH
by Drew Weaver 16 Mar '18

16 Mar '18

Hello, We've been running into some trouble finding Internet connectivity that will scale (100G) in Central Ohio. So we decided to try and find transport that would scale to other areas that have better Internet infrastructure (CLE, CIN, CHI, ATL, WDC/ASH), our success in this has been surprisngly limited. I know that AWS just put a facility in this area and Facebook is either building one or it is already completed so there must be someone either leasing fiber/transport or they built their own which means that somebody is still doing that kind of construction in this area. Has anyone completed any projects recently with any success at scale in Central Ohio? If so, could you share how you achieved this, either on-list or off-list? Thank you, -Drew

Google / GMail Geolocation
by Harry Reeder 15 Mar '18

15 Mar '18

Hi Folks, Wondering if anyone has a contact at Google who can help - I've a customer who's attempted to log in from one of our IPs (which comes from one of Cogent's /16 blocks) however they get an automated email response from Google saying that they're logging in from Hong Kong, and the login was prevented for security reasons (as someone may have their password). For reference, the whois response shows Washington DC, and refers to Cogent's rwhois which places us correctly at Telehouse London. Tools like Maxmind also have our location correct. Is there somewhere I can go to get this corrected for our leased IP ranges? (I am aware that the long term solution is to get our own IP space - I am working on that, I just don't have enough of a business case yet) Off-list replies also welcome. Thanks Harry

Office365 and a new IP address
by Paul Reichart 14 Mar '18

14 Mar '18

Wondering if anyone on the list has ever set up a mail filtering appliance or server on new IP address and had to deal with 451 messages from Office 365. We're processing a large volume of mail and seem to be throttled by O365. Seeing something like this: 451 4.7.500 Server busy. Please try again later from [x.x.x.x]. (AS77713180) [.....outlook.com ]. We own the IP block and the address itself is not on any block lists. It's been going on for a few days now, pissing off a lot of our customers. As expected O365's front line support is totally useless. Any advice would be appreciated!

Re: Proof of ownership; when someone demands you remove a prefix
by Naslund, Steve 13 Mar '18

The fact that it is a newer customer would make me talk to the RIR direct and verify that a dispute is really in progress. I would also look at some looking glasses and see if the prefix is being announced elsewhere, if so that might indicate that your customer is indeed stepping on a legit owner. I would also make it clear to the new customer that they are on thin ice here to light a fire under their process. Let them know that it is up to them to convince you that they are the legit owner. No one wants to lose a customer but they are threatening your business and putting you in legal jeopardy if they are not legit.

Does anyone have a contact for the SOC at centurylink? I've tried soc@centurylink and noc@centurylink, with no answer. For whatever reason, they're mangling IP address in abuse reports, which requires us to manually review every report. We'd really like them to stop, and just include the IP address in the body of the report. They seem to be the only ones that do this, pretty much all the other reports we get list a normal IP address.

Proof of ownership; when someone demands you remove a prefix
by Sean Pedersen 13 Mar '18

13 Mar '18

We recently received a demand to stop announcing a "fraudulent" prefix. Is there an industry best practice when handling these kind of requests? Do you have personal or company-specific preferences or requirements? To the best of my knowledge, we've rarely, if ever, received such a request. This is relatively new territory. In this case we have a signed LOA on file for that prefix and I've reached out to our customer to verify the validity of the sender's request. The sender claims to have proof that they are authorized to speak on behalf of the owner. I will wait until I hear from our customer before I consider a response to the sender. I don't get a real sense of legitimacy from the sender making the request. No one else announces the prefix. Nothing about the request appears to be legitimate, especially considering the sender. I thought about requesting they make changes to their RIR database objects to confirm ownership, but all that does is verify that person has access to the account tied to the ORG/resource, not ownership. Current entries in the database list the same ORG and contact that signed the LOA. When do you get to the point where things look "good enough" to believe someone? Has anyone gone so far as to make the requestor provide something like a notarized copy stating ownership? Have you ever gotten legal departments involved? The RIR?
