AT&T U-Verse Data Setup Convention
by Keith Stokes 30 Jul '15

30 Jul '15

I’m wondering if some can share their experiences or maybe there’s an AT&T person here who can confirm policy. I work for SaaS provider who requires a source IP to access our system to businesses. Normally we tell the customer to request a “Static IP” from their provider. That term makes sense to most ISPs. However, we’ve recently worked with an AT&T higher-up tech who told us that every U-Verse modem is locked to an address even when set to DHCP and will not change unless the unit is changed. Ordering a “Static IP” from them means your devices will individually get public addresses, which isn’t a requirement for us, isn’t quite as easy to add multiple devices and costs our customers more money. Here are my questions: 1. Is it really accurate that the customer’s address is tied to the modem/router? 2. For my curiosity, is this done through a DHCP reservation or is there a hard coded entry somewhere? 3. Do all U-Verse modem/routers behave the same way? This particular unit was a Motorola but the friends I’ve seen with U-Verse use a Cisco unit. --- Keith Stokes

Working with Spamhaus
by Bryan Tong 30 Jul '15

30 Jul '15

Hello All, SpamHaus has done us the favor of blacklisting all of our prefixes due to the issues with handful of IPs from customers we have removed from our network. They are now being unresponsive on helping us get these listings removed and we have a lot of legitimate customers who are no longer able to send email. If anyone has any advice on how to deal with these people. Please let me know here or off list. Thanks!

If yes, this might save some smaller networks some bandwidth. Martin

So far, it has not worked here anything like what that article describes. -- sed quis custodiet ipsos custodes? (Juvenal)

DOCSIS CMTS Systems
by Colton Conor 29 Jul '15

29 Jul '15

We are servicing more MDU customers that have older buildings. There is no CAT5E installed, so extremely old phone cable or coaxial TV cable seems to be our only inside wire options. There is no easy and inexpensive way to run new cable, so we must deal with what is available. We are very familiar with the VDSL2 offerings to be able to use the phone cable, but know nothing about CMTS solutions available.DOCSIS 3.0 capable modems seem to be much more inexpensive than VDSL2 capable modems. We are looking for recommendations on small CMTS systems for MDU's. I would expect we would want at least DOCSIS 3.0 capabilities, and I assume DOCSIS 3.1 is too new and expensive to deploy on a small scale (think 50 to 200 units per property). We would need the full solution to manage and maintain such an offering. I was thinking something like this might be a good fit: http://www.picodigital.com/product-details.php?ID=miniCMTS200a which is available new for $4500 online. For those of you deploying CMTS systems what do you use and recommend? I am not sure if there is a cable equivalent list to NANOG, but if so please let me know.

RE: Working with Spamhaus

I know this is going to sound worse than the spirit in which I offer it but... Step one might be to adjust the attitude from "Deal with these people" to something along the lines of "how might we best resolve the issue". No matter who you deal with, you will get much further with a good humble attitude rather than blame. It is my experience that if they list more than a very specific range of IP addresses on your network, you have a real problem. If you have a spammer at the top and bottom of a CIDR block then they may list the range, but I have had them lost two small ranges in the same /24 before... so I know they have very good specificity. I am sorry I can not offer you any specific steps or contact information to help you expedite the resolution, but I hope you will find some value in this advice. Perhaps, if your network is small and you control all your mail servers and you really are clean, you can configure thrm to relay through a smart host or SendGrid or etc. Good luck,Mike Sent from my Verizon Wireless 4G LTE smartphone -------- Original message -------- From: Bryan Tong <contact(a)nullivex.com> Date: 07/28/2015 8:06 PM (GMT-07:00) To: nanog(a)nanog.org Subject: Working with Spamhaus Hello All, SpamHaus has done us the favor of blacklisting all of our prefixes due to the issues with handful of IPs from customers we have removed from our network.
