The lwIP core code is distributed under a 3 clause BSD-style license. Confirmation has been received from Adam Dunkels that the existing public lwIP documentation is also covered by this license.

The original public eCos port included elements distributed under the eCos license.

As a result of the changes made by eCosCentric, portions of the eCos port of lwIP in eCosPro are covered by the eCosPro License.
