• 6to4 allows IPv6 packets to be transmitted over an IPv4 network. • It is described in RFC 3056: Connection of IPv6 Domains via IPv4 Clouds. • 6to4 is a router to router tunneling mechanism. • The tunnel is configured dynamically. • 6to4 is intended only as transition mechanism and is not meant to be used permanently. IPv6 Site B Identify hardware with OUI lookup in Wireshark - Comparitech May 01, 2019 Display IPV4 during tracing - Wireshark Q&A ip.addr is Ipv4. ipv6.addr is ipv6. a case for ipv4.addr and ip.addr is either? I can not see ipv4 and http, I can just see ipv6 and SSDP WHY ? Bogus IPv4 version. Dual Stack V4 and V6 interpretation. bogus ipv4 with ver 2.0.1. What is the capture filter for a specific IPv4 … Discovering IPv6 with Wireshark Discovering IPv6 with Wireshark June 16, 2010 Rolf Leutert Network Consultant & Trainer | Leutert NetServices | Switzerland SHARKFEST ‘10 Stanford University June 14-17, 2010.

IPv6 Training Since 2011 We have been training service providers and companies on IPv6 since 2011. Our hands on IPv6 classes cover basics to advanced including security. Make sure your organization has a plan to

Wireshark’s display filter engine doesn’t support prefix lengths for IPv6 addresses (not yet, at least) but you can use arithmetic comparisons to find public addresses, e.g. “ipv6.src >= 2000:: && ipv6.src < 4000::”.

Adding SSL and IPv6 to the mix complicates things. I’m in the process of making Wireshark’s public-facing services available over IPv6. It would be helpful to be able to test connectivity to each service before adding its corresponding AAAA record. Standard telnet clients support 6, but not SSL.

wireshark: fix rdepends issue Added a few more PACKAGECONF options Signed-off-by: IPv6 is short for "Internet Protocol version 6". IPv6 is the "next generation" protocol designed by the IETF to replace the current version of Internet_Protocol , IP Version 4 or IPv4. IPv6 was initially designed with a compelling reason in mind: the need for more IP addresses. Field name Description Type Versions; ipv6.6to4_gw_ipv4: 6to4 Gateway IPv4: IPv4 address: 1.4.0 to 3.2.5: ipv6.6to4_sla_id: 6to4 SLA ID: Unsigned integer, 2 bytes Wireshark’s display filter engine doesn’t support prefix lengths for IPv6 addresses (not yet, at least) but you can use arithmetic comparisons to find public addresses, e.g. “ipv6.src >= 2000:: && ipv6.src < 4000::”. The image above is a screenshot of the 6in4 protocol in Wireshark. As shown, the IPv6 packet is encapsulated within an IPv4 packet. This protocol is used with pre-configured tunnels, where IPv4 is used to route the traffic to the destination IPv6 network’s gateway and IPv6 is then used to route the packet to the intended destination. •The IPv6 prefix of all Teredo clients is 2001:0::/32 •The client resolves teredo.ipv6.microsoft.com to build the /64 prefix •The value 5ef5:79fd is the IPv4 Teredo server address: 94.245.121.253
