I’m comparing two Canon 1100D kit offers: one with the EF-S 18-55mm IS II and one listed as EF-S 18-55mm DC/III. What is the actual difference between these 18-55mm lenses, and does the “DC III” version include image stabilization?

Canon's overview for lenses with EF-S mounts does not use the descripton DC. The reason for why several third-party resellers use this description remains unclear to me
This list on Wikipedia suggests that the DC version of the lense is the basically the same, but without image stabilization.

Description
(source: Canon)
The Canon EF-S18-55mm f/3.5-5.6 III is a lightweight, compact standard zoom lens specifically for cameras that take EF-S lenses. Featuring a high-precision aspherical lens element, the lens compensates for chromatic aberrations that can occur while zooming to deliver high-resolution, high-contrast imaging performance. Through optimized lens positioning and coatings, the model greatly minimizes the flare and ghosting commonly associated with digital camera photography. It is a worthy successor to the EF-S18-55mm f/3.5-5.6 II and features a revamped external design.
The new Canon EF-S18-55mm f/3.5-5.6 IS II inherits the highly regarded optical design utilized in its predecessor, the EF-S18-55mm f/3.5-5.6 IS, released in September 2007. Featuring a high-precision aspherical lens element, the lens compensates for chromatic aberrations that can occur while zooming to deliver high-resolution, high-contrast imaging performance. Through optimized lens positioning and coatings, the model greatly minimizes the flare and ghosting commonly associated with digital camera photography. Furthermore, the EF-S18-55mm f/3.5-5.6 IS II includes an optimized control algorithm that has been aligned with the Image Stabilizer structure and characteristics, achieving image stabilization equivalent to approximately four shutter-speed stops.
Based on a shutter speed of "1/(focal length x 1.6)" seconds, considered the limit to prevent hand shake during hand-held photography.

The key difference is image stabilization. The Canon EF-S 18-55mm f/3.5-5.6 IS II has built-in IS, while the EF-S 18-55mm f/3.5-5.6 III is the non-stabilized version. “DC” does not appear to be Canon’s official naming here; sellers may be using it loosely, but the lens commonly referred to as “III” is the non-IS model.
Both are similar basic 18-55mm kit zooms for Canon EF-S cameras, with the same general focal range and aperture class. The supported answers do not show that the non-IS version is faster or has a larger aperture; both are typically f/3.5-5.6 lenses.
So if you specifically want a stabilized kit lens for handheld shooting at slower shutter speeds, choose the EF-S 18-55mm IS II. If the offer says “III” and does not explicitly say “IS,” assume it is the non-stabilized lens.
