[OT]Ispmap / isp locations / core routers
by Barry Murphy 18 Jul '05

18 Jul '05

Hey guys, I thought I'd start the week off with a brainstorm as I'm looking for a few additional things for ISPmap.co.nz . 1./ I'm after a geo location for each ISP's main core routers and an IP address for it too. 2./ I'm after a geo location for each ISP's headoffice. To gather this info, simply fire up http://status.fast.co.nz/metric.html , zoom in to the closest location to your office/router as possible, center it in the screen and mail me the details of latitude and longitude. http://status.fast.co.nz will soon become apart of ispmap, if you go directly to this URL you will see what my aim is, to have a country map (with the ability to filter by ISP) with the status of each ISP's network. Please mail back (Off list) in the following format: ISP: Contact: Logitude: Latitude: IP Address: Services effected: (optional, but would be nice to see what parts of the country and what services would be effected) Equipment: (optional, but eg cisco, I may add logos to the map later) Thanks. Barry

I agree 100% with Steve on this. I doubt that there are many providers that wish to publicise their internal network structure. A pretty map has very little relevance to a modern MPLS-based network without a view of the underlying signalling. All you'll see is the switched paths, not the physical infrastructure. There is such a thing as too much information - I see little point in letting an end user try to diagnose a network fault when said user has little or no understanding of network topologies and protocols, even at layer 3. Cheers, Gordon

Frame Relay services

I'd appreciate hearing from ISPs who provide connectivity using Frame Relay. Replies off list and please no diatribes about how crap Frame Relay is and how I should use technology X instead.

SPF Uptake in New Zealand
by Craig Whitmore 14 Jul '05

14 Jul '05

So you ask what is SPF? SPF (Sender Permitted From) is an anti-forgery method used with SMTP which stops people trying to send from your domain. Not designed for stopping spam, but helps reduce the amount of spam as well (stops people sending from other peoples domains). Spammers can add SPF records to their domains yes, (repeat: SPF doesn't stop spam but does a good job of it) but in the future may be improved to include trust factors (ie domain and SPF has been only around for 2 days and its sending 1000 emails to me... strange) There are quite a number of anti-forgery systems around at the moment, and the main ones are SPF, Sender-ID (Microsoft) and DomainKeys (Yahoo), SPF at the moment is the largest used worldwide. (over a million domain names having SPF records) The uptake in New Zealand is pretty small at the moment, but ISP's are starting to add SPF records for their domains. Xtra have added SPF rules for the xtra.co.nz Domain: v=spf1 ip4:210.86.15.0/24 ?all (host -t TXT xtra.co.nz) IHUG have added a SPF rule for ihug hosted domains to include: eg v=spf1 include:_spf.ihug.co.nz -all (host -t TXT _spf.ihug.co.nz) And a lot of Domains (see http://spam.co.nz/spf/working/) have started to add SPF Rules . This list is no where complete at the moment for .NZ (or other domainnames). Also quite a number of NZ domains have broken SPF records for various reasons which (if an ISP is testing for SPF will reject and cause bounces), so its quite important to make your rules correct (see http://www.spam.co.nz/spf/broken - This list is also quite imcomplete) I'm not saying SPF doesn't have its problems, but the major problem (at the moment) is forwarding emails . Ie user(a)ispa.com sends email to user(a)ispb.com and it gets forwarded to user(a)ispc.com. . If user(a)ispc.com checks for SPF it will fail as the user(a)ispa.com email address is coming from ISP B's email server. BUT mechanisms like SRS fix this problem. Mostly importantant is before SPF records are set up for a domain you must know how you users are using your domain. So maybe you think SPF is just something kids play around with and it will never be used for anything important and no one cares about it which is not so as its gaining momentum like just recently the IANA just gave SPF its own DNS RR (SPF) (see http://www.iana.org/assignments/dns-parameters) which will be used instead of the TXT records in the future to SPF records (maybe SPF v3 will use it only) More information can be read at: http://www.openspf.net/ and the mailing list and other information can be read at http://www.openspf.org/ Thanks Craig Whitmore www.spam.co.nz

> Just my 2c..... Nothing like a Friday morning rant... I need a V.... s/V/Beer/ ;) Cheers for that summary, it's helped me get my head around SPF, which I've flogged researching for the fear of adding False-Negatives possibilities on-top of my current SA setup (which, incidentally, has been flawless for a few months now). - Drew

I can see SPF being a big learning curve to the NZ ISP customer base, once ISP's start enforcing SPF. We still see lots of email from customers who have an ispa email set as their email address but are using our email server because they moved ISP's but didn't want to change email address. I would be surprised if any ISP's don't see this. SPF seems like a very good idea, and will work perfectly for personal domains, but for big ISP's, xtra/clear/ihug etc. It's going to cause a huge influx of unhappy customers if it ever gets implemented. - Simon

Hey folks, Noone has mentioned building the SPF strings :) I found this a while back: http://www.anti-spamtools.org/SenderIDEmailPolicyTool/Default.aspx It's a nice little (online) wizard from MS, which allows you to build the string without having to work out a geekcode-look-alike. AFAIK, they don't store info - just show you the SPF for what you enter. No comment on how effective SPF might be, but the wizard is handy if you don't wanna work out the syntax :) Cheers.
