In-depth analysis

IP blocking and especially IP range blocking is the built-in MediaWiki functionality that allows sysops to block particular IP numbers, preventing anybody using these IPs from editing.

Wikipedia recommends that "IP addresses should almost never be indefinitely blocked".[1] Additionally, it notes on the subject of range blocks that one should use "careful judgement and make them as brief as possible; this can affect over sixty-five thousand IP addresses (65,534, to be precise), potentially affecting millions of users."[2] As of June 2009, over 20,000,000 IP addresses have been blocked by Conservapedia. Since then it's got worse — they've been adding to the range blocked addresses in a big way.

The policy for the length of the deranged blocks is not clear: some sysops tend to block for six months or a year, others only issue infinite ones.

IP ranges[edit]

An IP (internet protocol) address is in some ways similar to a house address; it tells a computer where on the internet an object is operating, be it router, webserver, etc.

What does "/16" mean?[edit]

The long answer can be found in the Range block manual.[3] It also includes the "Idiot's guide to range blocks", which nicely breaks down some of the technical aspects.

The short answer is that (using Andy's test block as an example) "" blocks all IP addresses starting with "142.167". Or, to put it into an often-used form: "142.167.*.*" will be blocked.

As mentioned above, blocking IP addresses like this prevents all editors in these ranges from editing on CP. Now, that wouldn't be so bad, if the range was small enough. Unfortunately, "" is a range containing 65,534 individual IPs.

...and what about "/8"?[edit]

Counter-intuitively, "/8" covers a wider range than "/16".

Sticking to the example above, "" would cover "142.167.*.*" (equalling 65,534 IPs). "" however would cover "142.*.*.*" (equalling 16,777,214 IPs).

To prevent people from doing really dumb things, the MediaWiki software does not allow anything worse than "/16" blocks.

...and "/24"?[edit]

The "/24" range covers 254 IPs — the range of the fourth number of an IP. So "" covers "142.167.11.*". It's a more precise range than "/16" and should be the preferred choice of the two for normal cases.


Formally, there is no "/32" range, as this covers only one number.


On the other end, "/0" means every IP address available — if it was possible for these guys to block x.y.z.w/0, it would effectively render CP read-only.

September 2010[edit]

Within the first 5 days of September, TK issued the following long-term range blocks: - 1 year - Kirkland & Ellis LLP, Chicago, - 6 months - OUK Broadband IP Stream, U.K. - 1 year - M-NET TELEKOMMUNIKATIONS GMBH, Munich, Germany - 1 year - Videotron Ltee (C00503859) Quebec, Canada - 1 year - TELUS Communications Inc, BC, Canada (Unblocked by RobS on 6/13/2011) - 6 months - FRANCE TELECOM/SCR - 6 months - BT-CENTRAL-PLUS - 1 year - Deutsche Telekom AG, Germany - 1 year - Steadfast Networks, Chicago, IL - 1 year - SAVONLINNAN PUHELIN OY HILIMANET SERVICES, Finland - 1 year - Global Infrastructure Group Global Infrastructure Group (Unblocked by RobS on 6/13/2011)

In contrast, Karajou did not issue a single range block, whereas in 5 days TK has prevented some 704,000 IP addresses from editing on Conservapedia.

IPs per sysop[edit]

All blocks are of the "/16" sort unless noted otherwise.

  • Karajou: 12 blocks - 786,432 individual IPs
  • TK: 10 blocks - 655,360 individual IPs
  • Andy: 4 blocks - 262,144 individual IPs
  • Hojimachong: 1 block - 65,536 individual IPs
  • Niandra Jallen: 3 /24 blocks - 765 individual IPs

  • Total: 1,769,982 and counting...


Conservapedia has blocked more than 11,000,000 individual IPs. Because some of the blocks have expired, on Jan 13th, 2009, there were just 6,000,000 individual IPs blocked — roughly 0.144% of the net. The following pic shows the blocked IPs: the x-coordinate is the first octet of a address, the y-coordinate the second one, so a single point represents 65,536 addresses. If only one of these addresses is blocked, the point is colored white, the darker the point, the more addresses are taken out: black indicates that all addresses are blocked.

Light blue points are not blocked at all, while dark blue points represent special IP addresses, such as
