+What is IPv6?
+	Successor of currently used IP Version 4
+	Specified 1995 in RFC?  2460
+Why?
+	Address space in IPv4 too small
+
+Advantages?
+	stateless autoconfiguration
+	multicast obligatorisch
+	IPsec obligatorisch
+	Mobile IP
+	QoS ?
+	
+	Address Renumbering?
+	Multihoming?
+	AddressScopes?
+	smaller routing tables through G
+
+	simplified l3 header
+		64bit aligned
+		no checksum (l4 or l2)
+		no fragmentation at router
+
+Disadvantages
+	Not widely deployed yet
+	In most cases access only possible using manual tunnel
+	OS support not ideal in most cases
+		W2k?
+		Linux has support, but no IPsec in official tree -> USAGI
+		*BSD: full support (KAME
+	Application support not ideal in most cases
+		not supported: 
+		supported: bind8/9, apache
+
+Deployment
+	Experimental 6bone (3ffe::) has been active since 199x.
+	Uses slightly different Addressing Architecture (RFC2471)
+	
+Why isn't it widely used yet?
+	No immediate need in Europe / North America
+	Big deployment cost at ISP's (Training, Routers, ..)
+
+Technical: Address Space
+	IP Version 6 Addressing Architecture (RFC2373)
+		Format prefix, variable length
+			001: RFC2374 addresses, 1/8 of address space
+			0000 001: Reserved for NSAP (1/128)
+			0000 010: Reserved for IPX (1/128)
+			1111 1110 10: link-local unicast addresses (1/1024)
+			1111 1110 11: site-local unicast addresses (1/1024)
+			1111 1111: multicast addresses
+				1111 1111 flgs scop
+					flgs (0: well-known, 1:transient)
+					scop (0: reserved, 1: node-local, 2: link-local, 5: site-local, 8: organization-local, e: global scope, f: reserved)
+	Aggregatable Global Unicast Address Format (RFC2374)
+		3bit FP (format prefix = 001)
+		13bit TLA ID - Top-Level Aggregation ID
+		13bit Sub-TLA - Sub-TLA Aggergation ID
+		19bit NLA - Next-Level Aggregation ID
+		16bit SLA - Site-Level Aggregation ID
+		64bit Interface ID - derived from 48bit ethernet MAC
+
+		2001:0000::/29 - 2001:01f8::/29 IANA
+		2001:0200::/29 - 2001:03f8::/29 APNIC
+		2001:0400::/29 - 2001:05f8::/29 ARIN
+		2001:0600::/29 - 2001:07f8::/29 RIPE
+	loopback
+		::1
+	unspecified:
+		::0
+	embedded ipv4
+		IPv4-compatible address: 0::xxxx:xxxx
+		IPv4-mapped IPv4 (IPv4 only node): 0::ffff:xxxx:xxxx
+	anycast
+		allocated from unicast addresses
+		only subnet-router anycast address predefined (prefix::0000)
+
+
+Technical: Header
+
+	4bit Version: 6
+	8bit Traffic Class
+	20bit Flow Label
+	16bit Payload Length (incl. extension hdrs)
+	8bit next header (same values like IPv4, RF1700 et seq.)
+	8bit hop limit (TTL)
+	128bit source address
+	128bit dest address
+	
+	extension headers:
+		hop-by-hop options
+		routing
+		fragment
+		destination options
+		authentication
+		encapsulating security payload
+
+Technical: Layer 2 <-> Address mapping
+	Ethernet: No more ARP, everything within ICMPv6
+	No Broadcast, everything built using multicast.
+
+	all-nodes multicast address ff02::1
+	all-routers multicast address ff02::2
+	
+	
+Technical: Address Configuration
+	router discovery
+		routers periodically send router advertisements
+		hosts can send router solicitation to explicitly request RADV
+	prefix discovery
+		router includes prefix(es) in ICMPv6 router advertisements
+		other nodes receive prefix advertisements and derive their final address from prefix + EUI64 of MAC address
