Issues with Deploying IPv6 with IPSEC

ISSUESWITHDEPLOYINGIPV6 WITH IPSEC

The IP addressing structure describes the architecture of the network of a

particular system. The common Internet Protocol is typically the Internet Protocol version 4

(IPv4). The introduction of IPv6 protocol was intendedto solve most of the security limitations

thatexistedin IPv4 networks. One of the significantchanges was the necessary addition ofIP

Security (IPsec)in the IPv6 protocol. Nevertheless, the flexible nature of IPv6 protocol

introduces newlimitations. An itinerantIPprotocol can be includedinto the IPv6 protocol, and

in many organizations, security explanations for the protocol are still being developed.

Moreover, the flexible IPv6 couldbe dynamically configuredwhich may result in problems of

safety if they are incorrectly applied. Enhancing IPv6 may offer better security in certain areas.

However, some sectorsare prone to attacks.

IPSec enables the authentication of the sender, offer integrity security, as well as

encryption of IP packets for the privacy of the transmitted data. IPSec has always been an

optional feature in IPv4; however, it is compulsory in IPv6 protocol (Mudziwepasi., 2014). In

tunnel mode which essentially creates a VPN for communications such as network-to-network,

host-to-network as well as host-to-host, the entire packet is compressed into a new IP packet and

assigned a new IP header (Zamani., 2014). Since the cooperation and administration of IPSec

security defenses and the related secret keys are controlled by additional protocols and bring

about complexity, it is unlikely IPSec will be given a better support by IPv6 than it is with IPv4

originally.

IPv6 presents network sections that are pointedly broader than those many

organizations are used to. The current optional start length for an IPv6 subnet is /64 (264), which
