Our first inbound email via IPv6 (was spam!)
by Livingood, Jason 13 Jul '12

13 Jul '12

In preparation for the World IPv6 Launch, inbound (SMTP) email to the comcast.net domain was IPv6-enabled today, June 5, 2012, at 9:34 UTC. Roughly one minute later, at 9:35:30 UTC we received our first inbound email over IPv6 from 2001:4ba0:fff4:1c::2. That first bit of mail was spam, and was caught by our Cloudmark messaging anti-abuse platform (the sender attempted a range of standard spam tactics in subsequent connections). In the past several hours we have of course seen other messages from a range of hosts, many of which were legitimate email so it wasn't just spam! ;-) Since the Internet is of course more than just the web, we encourage others to start making non-HTTP services available via IPv6 as well.

There are three types of block pages that have been highlighted in the columns: oman_block_social - An Omani block page that specifies that the blocking was due to "societal and cultural norms of the sultanate." oman_block_laws - An Omani block page that specifies the reason for blocking was a violation of the law. india_block - An Indian block page that specifies the reason for blocking was a court order.

Routing Gone Wild: Documenting upstream filtering in Oman via India

job screening question
by William Herrin 12 Jul '12

12 Jul '12

Hi folks, I gave my HR folks a screening question to ask candidates for an IP expert position. I've gotten some "unexpected" answers, so I want to do a sanity check and make sure I'm not asking something unreasonable. And by "unexpected" I don't mean naively incorrect answers, I mean oh-my-God-how-did-you-get-that-cisco-certification answers. The question was: You implement a firewall on which you block all ICMP packets. What part of the TCP protocol (not IP in general, TCP specifically) malfunctions as a result? My questions for you are: 1. As an expert who follows NANOG, do you know the answer? Or is this question too hard? 2. Is the question too vague? Is there a clearer way to word it? 3. Is there a better screening question I could pass to HR to ask and check the candidate's response against the supplied answer? Thanks, Bill Herrin -- William D.

Requesting off-list contact from a verizon.net mail admin
by Andrew Jones 11 Jul '12

11 Jul '12

If someone who looks after verizon.net mail is listening, I would appreciate them contacting me regarding some issues we are having getting email through from our IP range. We've tried all the usual email channels (no response), and the online form insists that reverse DNS is missing (it's not) or the address is dynamic (it's not). Thanks, Andrew Jones Daraco Services
