An Address Management Mechanism for Blocking External Communications in IPv6 Networks 1

Outline Introduction Related work External communication blocking Implementation result Conclusions References 2

Introduction IPv4 address allocation has officially ended, IPv6 network users are increasing. Using RA(Router Advertisement) message to block external communication of a host. 3

Related work ICMPv6 (Internet Control Message Protocol for IPv6) RA 4

Related work(Conf.) SLAAC(Stateless Address AutoConfiguration) 5

External communication blocking 6

External communication blocking(conf.) 7

Implementation result 8

Conclusions The mechanism has blocked the external communication of the malicious host by using two modified RA messages. 9
