Abstract-The exhaustion of IPv4 addresses has forced the deployment of the new version of the Internet Protocol (IPv6). However, the migration to the new protocol is done gradually and with the due care for many reasons that include: cost, inclusion of support for IPv6 in existing applications, training of technical staff, lack of web content available over IPv6 from important providers, and obsolete devices not anymore supported by manufacturers. For those reasons, many transition mechanisms have been proposed, each one to fill distinct requirements, with different operational theory and availability according to the network environment. A performance evaluation of these mechanisms can help network administrators and researchers in their selection of the best transition technology for their environment. In this paper, we present a performance comparison of some transition mechanisms such as ISATAP, 6to4, and NAT64 in real testbeds with Debian, Windows 7, Windows 8, and Windows 10. For NAT64, two different tools were tested: TAYGA and Jool. We measure the OWD and the throughput for UDP and TCP for every mechanism, for both Ethernet and Fast Ethernet technologies. From this research, we can conclude that all the modern operating systems for PCs already have good support for IPv6, and a very similar network performance. Also, we can infer from our work that in controlled environments, native IPv4 has the best performance, closely followed by native IPv6. The difference is essentially due to the length of the IP header (20 bytes in IPv4 and 40 bytes in IPv6). The tunneling solutions chosen for this research (ISATAP and 6to4) have a similar performance, which is the lowest of the studied technologies, because of the additional IPv4 header in the tunnel.

The next generation of the Internet Protocol (IPv6) is currently about to be introduced in many organizations. However, its security features are still a very novel area of expertise for many practitioners. This study evaluates guidelines for secure deployment of IPv6, published by the U.S. NIST and the German federal agency BSI, for topicality, completeness and depth. The later two are scores defined in this paper and are based on the Requests for Comments relevant for IPv6 that were categorized, weighted and ranked for importance using an expert survey. Both guides turn out to be of practical value, but have a specific focus and are directed towards different audiences. Moreover, recommendations for possible improvements are presented. Our results could also support strategic management decisions on security priorities as well as for the choice of security guidelines for IPv6 roll-outs.

“…Routers, firewall, and security devices at the edge of the enterprise network may not be technically capable of inspecting IPv6 payload encapsulated within IPv4 packets entering or exiting the network. Three tunneling approaches are frequently applied-6t04 tunnels [2], Teredo [8], and IS ATAP [4] This can not be easilly used as user identifier.…”

Network monitoring is an essential task of network management. Information obtained by monitoring devices gives a real picture of the network in production including transmitted data volumes, top hosts, a list of frequently used applications etc. Deep analysis of data collected by monitoring can reveal network attacks or detect misuse of network services. In addition, Data Retention Act requires each ISP to track user's activities. Protocol IPv6 puts new challenges for network administrators in the context of user identification. Unlike IPv4, an IPv6 address no longer uniquely identifies a user or Pc. IPv6 address can be randomly generated and keeps changing in time. pes with IPv6stack can also communicate via predefined tunnels over IPv4 infrastructure. That tunneled traffic mostly bypasses network security implemented via firewalls. In this paper, we identify major monitoring and security issues of IPv6 connectivity and propose a solution based on SNMP and Netflow data that helps to uniquely identify users. The solution requires an extended set of monitoring data to be collected from network devices.We present a new data structure based on extended Netflow records. Feasibility of the approach is demonstrated on the Brno University of Technology (BUT) campus network.

Intra-Site Automatic Tunnel Addressing Protocol (ISATAP)

Abstract: The Intra-Site Automatic Tunnel Addressing Protocol (ISATAP) connects dual-stack (IPv6/IPv4) nodes over IPv4 networks. ISATAP views the IPv4 network as a link layer for IPv6 and supports an automatic tunneling abstraction similar to the Non-Broadcast Multiple Access (NBMA) model.
