직관적인 설명과 함께 전문성을 키울 수 있는
완벽한 IPv6 가이드북!

이 책은 “Cisco Press Fundamentals 시리즈”의 일부이다. 이 시리즈의 책은 네트워크 전문가들에게 새로운 네트워킹 기술을 소개하며, 네트워크 토폴로지, 적용 개념 예, 프로토콜 및 관리 기술을 다룬다. 점점 더 많은 정부 기관, 회사들이 IPv6로의 전환을 진행하고 있다. IPv6는 모든 종류의 디바이스가 네트워크상에서 어떻게 통신하는지 정의하는 차세대 프로토콜이다. 이 『네트워크 엔지니어를 위한 차세대 인터넷 프로토콜 IPv6 기본원리』는 완전하게 개정된 판으로 IPv6 네트워크를 적용하고 운영하는 데 필요한 지식과 기술을 친절하고 이해하기 쉬우면서도 완전하게 소개한다.

최고의 네트워킹 강사인 릭 그라지아니는 여러분이 IPv6에 익숙해질 수 있도록 기본 개념을 단계별로 알기 쉽고 명확하게 설명하여, 필요한 모든 상세 정보를 제공한다. 여러분은 IPv6가 왜 필요하게 되었는지, 어떻게 만들어졌는지, 어떻게 동작하는지, 클라우드에서 모바일 및 IoT에 이르는 환경에서 어떻게 선택받은 프로토콜이 되었는지 알게 될 것이다. 그라지아니는 IPv6 주소 지정, 설정 옵션 및 IPv6 EIGRP 및 OSPFv3(고전적 설정과 address family)를 포함한 라우팅 프로토콜을 완전하게 소개한다. 그리고는 그 범위를 기반으로 IPv6 및 프로세스와 관련된 보다 깊은 내용을 설명한다.

이번 제2판에서는 네트워크에 IPv6를 적용하는 방법에 대해 완전히 개선된 내용을 설명하며, IPv6/IPv4 통합, 동적 주소 할당, 네트워크 및 호스트의 관점에서 본 IPv6 이해를 포함하고 있다. 또한, Stateless Address Autoconfiguration(SLAAC), DHCPv6 및 solicited node multicast 주소의 장점과 같은 주요 주제에 관한 개선된 내용을 확인할 수 있을 것이다.

더욱 심층적인 이해를 위해 그라지아니는 책 전반에 걸쳐 시스코 IOS, 윈도우, 리눅스 및 맥 OS에 대한 명령 구문뿐만 아니라 다양한 예제, 다이어그램, 설정 팁, 백서 및 공식 RFC에 대한 최신 링크를 제공한다. 릭 그라지아니는 카브릴로대학에서 컴퓨터 과학, 정보 과학 및 네트워킹 과정을 가르치고 있다. 그는 정보 기술분야에서 30년 이상 업무와 교육 경험이 있으며, 현재 시스코 및 기타 주요 고객을 위한 컨설팅 업무를 하고 있다. 그라지아니는 이 책의 초판과 IPv6 Fundamentals Live Lessons 비디오 코스의 저자이다. 또 Cisco Press에서 출판된 〈Implementing Cisco IP Routing (ROUTE) Foundation Learning Guide〉, 〈Accessing the WAN, CCNA Exploration Companion Guide〉, 〈Routing Protocols and Concepts, CCNA Exploration Companion Guide〉의 공동 저자이다.
