IPv6 Address Planning

Colophon

The animal on the cover of IPv6 Address Planning is the Pander’s ground jay (Podoces panderi), also known as a chough thrush, grey ground jay, or Turkestan ground jay. These birds are members of the Corvidae family, which includes crows and jays. They can be found in central Asia, particularly the countries of Kazakhstan, Turkmenistan, and Uzbekistan.

They are small birds with slim, slightly curved beaks and sand-colored plumage. Their tails are black, and they also have a large black spot on their breast. Pander’s ground jays live in desert habitats with plenty of bushes for cover, but will also forage near human settlements.

As their common name suggests, ground jays spend most of their time on the ground, and are indeed more adept at running than flying. Their beaks are well adapted for digging and probing the earth as they forage for a diet of insects, seeds, and plant matter.

Birds of the Corvidae family are very intelligent, with a brain-to-body mass ratio equal to that of great apes (and only slightly lower than humans).
