IPv4 Exhaustion
by Philip D'Ath 11 Dec '06

11 Dec '06

I attended a very interesting presentation today by Tony Bain, one of the key IETF IPv6 chairs. He says that the rate of /8's being allocated is increasing exponentially at that moment (22 were allocated in 18 months [till July 2005], leaving just 64 available worldwide), and the prior estimate of when IPv4 address was going to be exhausted of 2020 has been revised to 2009 - as in three years away, and that IPv4 address space is likely to take on a much more commercially tradable value as it becomes very rare (like oil). For existing players in the market this doesn't mean much. However for expanding networks this is going to put a serious crimp in their plans. I polled a lot of players in the NZ market about 6 months ago and plans for IPv6 deployment were almost non-existent. There is an older article he wrote here: http://www.cisco.com/web/about/ac123/ac147/archived_issues/ipj_8-3/ipv4. html We really need large commercial transit players like Global Gateway, TelstraClear, AT&T, UUNet, AsiaNetCom, and Sprint to start offering dual stack IPv6 connections to downstream ISPs, and for ISPs to start allowing clients to connection via IPv6, including via DSL. We really need to get critical infrastructure, like DNS, fully IPv6 enabled. The .nz domain isn't even reachable via IPv6 addresses yet. Now I know the shared registry system has IPv6 support now, but it is limiting in that you must still supply IPv4 addresses. You can't supply only IPv6 glue records. What happens when you can't get IPv4 addresses to use for glue? Also the majority of the registries out their offer very poor IPv6 support - as in no IPv6 connected DNS servers, and an inability to easily add IPv6 AAAA records.

Moving DNS providers - best practice.
by Simon Lyall 10 Dec '06

10 Dec '06

After a few recent instances I am getting sick of companies who transfer their DNS/Servers from one provider to another and then wonder why the old data is still cached by 3rd parties for 24 hours (or whatever). How do people feel about a "best practice" document on this that we could encourage people to follow ( perhaps the DNC could publish) for people moving their domain between providers. Just the basics like, dropping the TTLs, getting all the servers data in the right order etc?

NO contact list
by Gerard Creamer 10 Dec '06

10 Dec '06

There now appear to be two versions of this list. http://www.tcn.bowenvale.co.nz/content/view/49/40/ and http://www.usenet.net.nz/noc/index.html We have recently been assigned a public AS and I thought we should probably go on the list - as we're growing our things breaking will have a wider impact and other NOs might want to get hold of us. I have no issue with being woken up in the middle of the night when our things break. I have a strong objection to being woken up when someone elses things break. Personally I like the (mostly) unlinked anonymity of the list at usenet.net.nz, as it's less likely to be some kid who has no idea what an AS is calling at 2am because the gaming server they're using in suddenly unreachable (probably due to some reason other than our network being broken). Sure, the kid might ultimately pay my wages, but they're sure as hell not my customer... I emailed Simon Lyall yesterday to ask to go on the list at usenet.net.nz - is this still going to be considered the NO list? I know there's no king and all that jazz, but some direction for a newbie AS NO would be appreciated... For the record, here's our guff: Name Netspace Services Limited Domains netspace.net.nz ASN(s) 9733 Phone Number(s) +64 4 917 8098, 0800 NETSPACE (0800 638 772) Clueful People Gerard Creamer Direct Email noc(a)netspace.net.nz Hours Office Thanks, Gerard

Mainly: - delivery temporarily suspended: connect to mta.xtra.co.nz - connect to mta.xtra.co.nz[210.54.141.1]: server dropped connection without sending the initial SMTP greeting Has anyone seen any of these issues and knows anything about them? I just trying to contact XTRA's administrators, but no response. I have had a good response back from the corporate side of XTRA, which is assuring. Regards and Thanks, Simon

And that we'd particularly welcome a proposal on, eg, best practices in running a mail server, or coping with the ever increasing volume of spam without rejecting all the legitimate mail. Proposals of other relevant talks (see the original CFP) are also welcomed, but be quick as we'd like to finalise the programme before Christmas so the speakers know what their summer homework is.

<metoo/> Given that (apparently) along with many other ISPs, Ihug also seem to have trouble with Xtra's inbound mailservers, perhaps I should say "could someone from Xtra please contact me ON list". (Yes we're all on fire trying to deal with Image Spam, but refusing valid mail just makes it worse...) -Martin -- Martin D Kealey, ihüg Systems Engineer

IN case this is lost amongst the flurry of flames, here's who to contact. It does appear lost as someone did ask again about 20 mins after Ted posted this (mind you I have only date stamps to go by). Lots of you are still flaming about it. May I also point out that Ted has in the past responded to this list stating he's happy to be contacted about this. eg http://list.waikato.ac.nz/pipermail/nznog/2005-August/010430.html http://list.waikato.ac.nz/pipermail/nznog/2005-January/009460.html regards lin ---------- Forwarded message ---------- Date: Thu, 7 Dec 2006 13:52:23 +1300 From: Ted Grenfell <Ted.Grenfell(a)telecom.co.nz> To: Simon <greminn(a)gmail.com>, nznog(a)list.waikato.ac.nz Subject: Re: [nznog] Xtra Email Administrators So as always, you're all welcome to call me direct if you've an Xtra query that you don't want to send via postmaster etc. -- Kind Regards, Ted Grenfell Online Services Mgr (acting) T +64 9 359 5854 (extn 93254) F +64 9 377 0781 M +64 27 443 5455 E ted.grenfell(a)telecom.co.nz W www.telecom.co.nz Level 11, Telecom House, 8 Hereford Street, Private Bag 92028, Auckland CBD, New Zealand ________________________________ "This communication, including any attachments, is confidential.

We are also seeing issues since late November. I emailed postmaster(a)xtra from elsewhere on 1 December, with no response so far. Typical log: Dec 7 14:19:26 skinner postfix/smtp[19226]: connect to mta.xtra.co.nz [210.54.141.1]: server dropped connection without sending the initial greeting (port 25) Typical telnet: $ telnet mta.xtra.co.nz 25 Trying 210.54.141.1... Connected to mta.xtra.co.nz. Escape character is '^]'. Connection closed by foreign host. $ The above is the most common behaviour, but apparently the connection does stay open properly from time to time (I had to send a bunch in a row to get this): Dec 7 14:28:34 skinner postfix/smtp[19322]: 187FFA9EF2B: to=<jkhhlkhkjh(a)xtra.co.nz>, relay=mta.xtra.co.nz[210.54.141.1], delay=27, status=bounced (host mta.xtra.co.nz[210.54.141.1] said: 550 Invalid recipient: <jkhhlkhkjh(a)xtra.co.nz> (in reply to RCPT TO command)) We also sometimes get "421 Service not available" before it drops the connection, and sometimes we even get connection refused. But when we're really lucky: 220 mta01.xtra.co.nz ESMTP server ready Thu, 7 Dec 2006 14:41:34 +1300 220 mta06.xtra.co.nz ESMTP server ready Thu, 7 Dec 2006 14:43:01 +1300 So, yeah, it looks like something might be up.
