This project is not part of the GNU Project.

lwIP is a small independent implementation of the TCP/IP protocol suite that has been initially developed by Adam Dunkels and is now continued here.

The focus of the lwIP TCP/IP implementation is to reduce resource usage while still having a full scale TCP. This makes lwIP suitable for use in embedded systems with tens of kilobytes of free RAM and room for around 40 kilobytes of code ROM.

Main features include:
- Protocols: IP, ICMP, UDP, TCP, IGMP, ARP, PPPoS, PPPoE
- DHCP client, DNS client, AutoIP/APIPA (Zeroconf), SNMP agent (private MIB support)
- APIs: specialized APIs for enhanced performance, optional Berkeley-alike socket API
- Extended features: IP forwarding over multiple network interfaces, TCP congestion control, RTT estimation and fast recovery/fast retransmit
- Addon applications: HTTP server, SNTP client, SMTP client, ping, NetBIOS nameserver

Contrib code (including example ports and addon applications) is available here:

For all of you using the 1.4.1 "stable" release: in git master, there have been numerous bugfixes and improvements (including dual-stack IPv6 support) since that release, so please consider using git. Hopefully, there will be a beta for 1.5.0 soon, followed by a release...
