BGP next-hop self benefits
by craig washington 04 Dec '17

04 Dec '17

Hello everyone, Question, what are the true benefits to using the next-hop self feature, doesn't matter what vendor. Most information I see is just to make sure you have reach-ability for external routes via IBGP, but what if all your IBGP knows the eBGP links? Is there a added benefit to using next hop self in this situation? Any feedback is much appreciated, either for the question specifically or whatever else you got 😊, L3VPN's or underlying technology that has to have that. Thanks

Hi, is there anyone from Korea Telecom on this list ? Trying to contact anyone in NOC, it seems that they blacklisted our complete AS (198252) and they are not responding to e-mail. Our customer support is overwhelmed with complaints about non reachable servers hosted in their network. Any help is appreciated. Sincerely, Igor Krneta Elta Kabel d.o.o.

Re: Incoming SMTP in the year 2017 and absence of DKIM (fwd)

Yup, with the chain typically having no more than one or two links, since legit forwarding of the kind that might break DKIM is pretty rare more than two deep. >If I do understand correctly, I think that it's intriguing.

I thought it was pretty clever, but like I said, the large mail systems that developed ARC wanted to put the control with the recipients, not the senders. R's, John

Incoming SMTP in the year 2017 and absence of DKIM
by Eric Kuhnke 02 Dec '17

02 Dec '17

For those who operate public facing SMTPd that receive a large volume of incoming traffic, and accordingly, a lot of spam... How much weight do you put on an incoming message, in terms of adding additional score towards a possible value of spam, for total absence of DKIM signature?

aggregate6 - a fast versatile prefix list compressor
by Job Snijders 01 Dec '17

01 Dec '17

Dear NANOG, I re-implemented the venerable 'aggregate' tool (by Joe Abley & co) in python under the name of 'aggregate6'. The 'aggregate6' tool is faster and also has IPv6 support. https://github.com/job/aggregate6 Installation is can be done through 'pip', or your operating system's package manager (if they carry the 'aggregate6' tool). $ pip install aggregate6 Example use: $ echo 10.0.0.0/16 10.0.0.0/24 2000::/4 3000::/4 | aggregate6 10.0.0.0/16 2000::/3 Note that 'aggregate6' can also be imported as module in your own python project: >>> import from aggregate6 import aggregate >>> aggregate(["10.0.0.0/8", "10.0.0.0/24"]) ['10.0.0.0/8'] >>> Related to the above example, NTT uses 'aggregate6' as library in their network automation toolchain to help compress firewall rules. When using a dump from the IPv4 Default-Free Zone, it appears that 'aggregate6' can deaggregate that list ~ 50 times faster than 'aggregate'. However the tradeoff is that 'aggregate6' uses a bit more memory. Aggregate6 has been tested with pypy, python2 and python3; and can be used both from the command line or as python module. Aggregate6 is published under the 2-Clause BSD license. Kind regards, Job

ccTLDs - Become a Registrar
by Ryan Finnesey 01 Dec '17

01 Dec '17

I was wonder if anyone within the group has done this research and might be able to save me a bit of time. I am in the process of putting together a new Registrar and we would like complete ccTLD coverage. I know for example CIRA (.ca) has a Canadian Presence Requirement and we have formed a Canadian Corporation to meet this requirement. I am hoping to find what other TLD operators may have similar requirements. Cheers Ryan
