subscription services

While dnsbl.net.au is offering this service on a not-for-profit basis. The subscription fees are strictly a cost recovery measure that helps support the current and future 24x7 operational requirements of this service.

Other costs that dnsbl.net.au must cover include 24x7 service monitoring; server maintenance and connectivity; help-desk support; second-level 24x7 on-call engineering; and ongoing maintenance of the service database server software that powers the dnsbl.net.au service.

Ongoing legal advice and services also need to be covered.

Metcalfe's Law
Sun - The Net Effect
The inventor of Ethernet, Metcalfe was among the first to herald the value and exponential power of connecting more and more machines to the network. Metcalfe's Law indicated that, however many devices you connect, the value of the resulting network could be expressed as the number of devices -- squared.
Context Magazine
Conventional wisdom is that a remarkably powerful effect known as Metcalfe's Law is driving the growth of the Internet. The law says that the value of a network grows in proportion to the square of the number of users, which means that, once a network achieves a certain size, it becomes almost irresistibly attractive.
or just google it

Considering Metcalfe's Law (thanks Justin!) it seems that for a project like dnsbl.net.au to be successful, it will need a large user base.

The human resources time consumed to carry out the software development, testing, configuration, database management and client management, as well as the direct costs associated with bandwidth provisioning, server hardware and redundancy planning, are significant.

So all that needs to be paid for somehow.

Unlike other companies who I have assisted with those tasks over the years, in various ways, I won't start the service out as a 'free service' to only convert it to a 'paid service', when it's all operational with a significant client base.

It will be a paid service from the start, and it will remain a paid service.

The subscription table below is targeted at getting as many people as possible participating, hopefully, at a reasonable price for their particular organisation and circumstances.

Direct DNS Query Method - TABLE A (Monthly) Pricing

$3.00 per 10,000 queries (or part thereof),
when charged monthly in arrears directly to a Credit Card

$2.00 per 10,000 queries (or part thereof),
when charged monthly in advance directly to a Credit Card

Australian clients, are subject to GST, so add 10%

query defined as any single logfile event in rbldnsd logfile
ie all separate TXT, A, AAAA or ANY name server request types.
Further, querying t1.dnsbl.net.au only, is way cheaper,
than querying all 12 sub zones separately.

eg averaging 20,000 queries per day is 600,000 per month
and paying monthly in arrears
Non Australian client pays 600,000 * $3.00 / 10,000 = $180.00
Australian client pays additional 10% GST = $198.00

eg 1,000,000 queries per month, paid in advance
Non Australian client pays 1,000,000 * $2.00 / 10,000 = $200.00
Australian client pays additional 10% GST = $220.00
