Internet and Routing
Geoff Huston's Website	One of my favorite sites. Insightful monthly articles, papers and presentations, and active views into the public BGP table and IPv4/IPv6 address allocations. Access to a few nice tools, too.
Internet Assigned Numbers Authority (IANA)	Your first stop when researching IP address statistics and allocation policies.
APNIC ARIN RIPE LACNIC AfriNIC	The sites of the five Regional Internet Registries. Required reading for anyone keeping up with address allocation issues and statistics, plus some good tutorials and tools.
Estoile.com	An excellent list of lists for standards, papers, tutorials, and code on a wide variety of subjects. BGP, MPLS, IPv6, DHCP, VoIP, SSH, IPSec, and many other topics are covered. A good place to begin general research.
IPv6
Go6	An extensive, up-to-date listing of IPv6 news and technical articles.
The IPv6 Portal	Good worldwide coverage of IPv6 industry news, and a listing of IPv6 Task Forces around the globe.
Cisco Systems' IPv6 Site	Case studies, white papers, presentations, and practical technology and design guides. Cisco also has a separate site focused on the Federal government.
IPv6 Forum	Keep up with IPv6 Forum Summits around the world
Microsoft's IPv6 Site	Articles on Microsoft support and objectives, plus useful information on home routing, Teredo, ISATAP.
Government Computer News	News bulletins focusing on IPv6 in the United States government.
IPv6Style	IPv6 news, primarily focused on Japan. A good source when you are interested in seeing how IPv6 is being used in practical applications.
IPv6 Promotion Council of Japan	News about IPv6 development activities in Japan.
The TAHI Project	TAHI produces the premier IPv6 conformance test suites used worldwide.
The USAGI Project	IPv6 stacks for Linux.
The KAME Project	IPv6 stacks for FreeBSD and its variants, plus a nifty dancing turtle.
The WIDE Project	WIDE (Widely Integrated Distributed Environment) runs numerous R&D projects employing IPv6.
MPLS
MPLS-VPLS Resource Center	Industry news and a good collection of white papers.
Standards Bodies and Working Groups
Internet Engineering Task Force (IETF)	Your primary source for technical information on IP. You can search for RFPs by number, search for Internet-drafts, or look for RFCs and Internet-drafts by working group.
Institute of Electrical and Electronics Engineers (IEEE)	The IEEE develops and promotes a vast number of standards, although we in the IP field think primarily of Ethernet (IEEE 802.x) and MAC addresses when we think of the IEEE.
International Telecommunication Union, Telecommunication Sector (ITU-T)	The third of the "big three" standardization bodies, (IETF and IEEE being the other two) for IP networkers. Lots more than just IS-IS and the unavoidable OSI model.
MFA Forum	The MFA (MPLS, Frame Relay, ATM) Forum works to develop specifications for those three technologies.
WiMAX Forum	The WiMAX Forum promotes and helps specify 802.16 wireless broadband technology.
3rd Generation Partnership Project (3GPP)	3GPP focuses on standards development of GSM and related mobile technologies.
