Our look is the result of reader comments, our own experimentation, and feedback from distribution channels. Distinctive covers complement our distinctive approach to technical topics, breathing personality and life into potentially dry subjects. The animal on the cover of IPv6 Essentials is a rigatella snail. The rigatella snail, or Eobania vermiculata, is native to the Mediterranean region, especially to Turkey and Crete. The snail lives in gardens, hedges, and dunes, where it feeds on vegetation. The snail got its scientific name because the rings on its shell resemble vermicelli (a type of pasta). It is also sometimes called the "noodle snail."

Rigatella snails commonly have about five brown rings on their cream-colored shells. Their eyes sit on stalks, or tentacles, which protrude from their heads. The snails are 17 to 21 millimeters high and 20 to 25 millimeters wide. They move by rhythmically contracting their muscular base, or foot. As they move, the snails secrete a colorless discharge that creates a type of carpet, which protects them from the surfaces on which they travel. This discharge is so effective that a snail could crawl along the blade of a razor and not be cut.

Rigatella snails are edible. They are one of the most popular types of snail used to make the European delicacy, escargots. Claire Cloutier was the production editor for IPv6 Essentials. Leanne Soylemez and Claire Cloutier were the copyeditors. Ann Schirmer was the proofreader. Sarah Sherman provided editorial assistance. Ann Schirmer, Emily Quill, and Jeffrey Holcomb did quality control checks. Claire Cloutier, Sarah Sherman, Philip Dangler, Leanne Soylemez, Darren Kelly, and Judy Hoer were the compositors. Ellen Troutman-Zaig wrote the index.

Hanna Dyer designed the cover of this book, based on a series design by Edie Freedman. The cover image is a 19th-century engraving from Cuvier's Animals. Emma Colby produced the cover layout with QuarkXPress 4.1, using Adobe's ITC Garamond font.

David Futato designed the interior layout. This book was converted to FrameMaker 5.5.6 with a format conversion tool created by Erik Ray, Jason McIntosh, Neil Walls, and Mike Sierra that uses Perl and XML technologies. The text font is Linotype Birka; the heading font is Adobe Myriad Condensed; and the code font is LucasFont's TheSans Mono Condensed. The illustrations that appear in the book were produced by Robert Romano and Jessamyn Read, using Macromedia FreeHand 9 and Adobe Photoshop 6. The tip and warning icons were drawn by Christopher Bing. This colophon was written by Linley Dolby.
