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 TCP/IP Network Administration is a land crab. Land crabs are found in tropical America, West Africa, and the Indo-Pacific region where they can be found living in burrows in fields, swamps, and mangrove thickets. They occasionally are found as far as five miles inland, returning to the sea to spawn. Land crabs are a subgroup of over 4,500 species of crabs. Classified with shrimp, lobster, and crayfish, crabs differ from these in their tail structure. Unlike the rest of their order, crabs' tails are curled under their thorax. In addition, their carapaces tend to be unusually broad. Though land crabs in the United States commonly grow to weigh no more than 18 ounces and measure 4 or 5 inches across, crabs in general range in size from less than a centimeter across to the largest, the Japanese spider crab, whose claws can span 12 feet. Emily Quill was the production editor and copyeditor for TCP/IP Network Administration, Third Edition. Jeffrey Holcomb and Jane Ellin provided quality control. Derek Di Matteo and Sue Willing provided production assistance. Tom Dinse wrote the index.

Edie Freedman designed the cover of this book, using a 19th-century engraving from the Dover Pictorial Archive. Emma Colby produced the cover layout with QuarkXPress 4.1 using Adobe's ITC Garamond font.

Melanie Wang designed the interior layout, based on a series design by David Futato. Neil Walls converted the files from Microsoft Word to FrameMaker 5.5.6 using tools created by Mike Sierra. 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.
