Private-to-public IP주소 변환을 위해서는 NATs(Network Address Translators)와 같은 Gateway System(주로 방화벽제품에서 사용)을 사용하여야 합니다. 즉, 내부적으로 private address를 사용하도록 설정되어 있는 전산기가 외부 인터넷상의 전산기와 통신하려 할때는, 이 gateway 시스템에서 private IP주소를 public IP주소로 변환해 줍니다. 이때 gateway 시스템은 적정 수량의 필요한 public IP주소 pool을 유지하고 있어야 하므로, 이에 필요한 public IP주소는 인터넷주소할당조직(Internet Registry)으로부터 할당받아야 합니다. 이 private 주소 사용에 있어서의 장점은 KRNIC, ISP등 누구에게도 주소공간 할당 신청을 하지 않음으로서, 까다로운 심사절차 를 거치지 않아도 됩니다. 즉, 기업내부의 모든 host수를 조사하고, CIDR/VLSM을 적용한 세밀한 networking plan을 세우고, 상대적으로 다루기 어려운 OSPF같은 프로토콜을 사용하여야 하는 등의 불편이 따르지 않게 됩니다. 조직내부 IP주소공간 관리 편의를 위해, 필요이상으로 충분히 넉넉한 주소공간을 자유롭게 사용할 수 있습니다. 즉, 5개의 host가 필요한 subnet에 대해서도 미래를 대비하여 /24를 할당할 수 있습니다. 수시로 변하는 조직변동, 전산기들의 이동, 재배치 등등에 대해서도 별로 걱정할 필요로 없습니다. Private IP주소를 사용하게 되고, 주로 NATs 시스템이 방화벽기능을 포함하고 있으므로, 상대적으로 보안성이 강화됩니다. 그러나, 전세계 인터넷도메인이름 시스템과 연결되는 external용과 기업 내부용의 internal Domain Name server를 운영해야 할 것이며, 외부 공개용으로 반드시 public IP주소가 필요한 시스템과 그렇지 않은 시스템으로 구분하여, 외부 공개용 시스템에는 public IP 주소를 static하게 지정하여야 할 것입니다. 최근 private IP주소를 활용하는 라우터, 시스템 등이 많이 출시되고 있는 추세이므로, 이의 사용을 적극 권장한다. 보다 자세한 내용은 RFC1597을 참조할수 있습니다. === IP (Internet Protocol) header === * IP datagram은 다음과 같은 형식을 가진다. || '''0''' || '''1''' || '''2''' || '''3''' || '''4''' || '''5''' || '''6''' || '''7''' || '''8''' || '''9''' || '''10''' || '''11''' || '''12''' || '''13''' || '''14''' || '''15''' || '''16''' || '''17''' || '''18''' || '''19''' || '''20''' || '''21''' || '''22''' || '''23''' || '''24''' || '''25''' || '''26''' || '''27''' || '''28''' || '''29''' || '''30''' || '''31''' |||| '''Description''' || |||||||| 4bit Version |||||||| 4bit Header length / 4 |||||||||||||||| 8bit Type of service (TOS) |||||||||||||||||||||||||||||||| 16bit Total length (in bytes) ||<|5> 20 bytes ||<|6> 20~60 bytes || |||||||||||||||||||||||||||||||| 16-bit Identification |||||| 3-bit Flags |||||||||||||||||||||||||| 13bit Fragment offset || |||||||||||||||| 8bit Time to live (TTL) |||||||||||||||| 8bit Protocol |||||||||||||||||||||||||||||||| 16bit Header checksum || |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||| 32bit 출발지 IP 주소 || |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||| 32bit 목적지 IP 주소 || |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||| Options (if any) || 0~40 bytes || |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||| Data |||| Total length - Header length || * ''4-bit Header length''는 4의 배수로 해석한다. 즉, 1이 4바이트를 뜻한다. 최대 4-bit로 15까지 값을 지정할수 있으므로 15x4=60 bytes가 최대값이고 이것은 "''Options (if any)''" 가 60-20=40 bytes를 넘지 못한다는 의미이기도 하다. * ''8-bit Protocol'' 항목에는 다음의 값들을 사용할수 있다.
