Gan Ane nubi mau tanya ttg IPv6 ini

ane masih memulai belajar IPv6 tp.
ane masih penasaran ttg IPv6 ini :
- klo IPv6 itu apakah bisa di routing dengan IPv4 ga?..
- apa IPv6 bisa digunakan untuk teknik VLSM ?..
- trus klo seandainya si gateway(dapat IP Public) pake IPv6,trus apakah client bsa masih menggunakan IPv4 ? dengan menerapkan NAT untuk client ..
- Apakah IPv6 memiliki Private address seperti IPv4 dahulu ?..
- dan yang terakhir,,apakah IPv6 bisa mengakses web atau suatu PC/server (via remote) yang menggunakan IPv4..
Sekian pertanyaan ane gan,,ane masih bingung tentang implementasi IPv6.
semoga agan" disini bisa memberikan pencerahan..

Pertanyaan ane jawab dibawah ini gan,..
# Routing IPv6 didalam IPv4 menggunakan 6to4 tunnel dengan cara :
1. Membuat tunnel IPv4 + Define Source Destination Address
2. Membuat PTP IPv6
3. Berikutnya Routing bisa static bisa dynamic gan....
Contoh gan ...
interface Tunnel101
description TUNNEL6-SPRINTv6
ip unnumbered Loopback6
ipv6 address 2001:440:EEEE:FF5B::2/64
ipv6 enable
tunnel source 202.53.251.197
tunnel destination 144.228.240.165
tunnel mode ipv6ip
!
interface Tunnel103
description TUNNEL6-HURRICANE-CALIFORNIA
no ip address
ipv6 address 2001:470:1F01:FFFF::17AF/127
ipv6 enable
tunnel source 202.53.251.195
tunnel destination 64.71.128.83
tunnel mode ipv6ip
# VLSM support
Layaknya IPv4, IPv6 juga memenuhi kebutuhan CIDR/VLSM yang memungkinkan untuk pembagian dan pengalokasian IPv6 menjadi lebih spesifik untuk di routingkan secara kesatuan.
IPv6 juga memiliki kelas sebagaimana IPv4 diantaranya (Sumber IANA):
- Aggregatable Global Unicast Addresses dengan bit awal 001 (2000::/3)
- Link-Local Unicast dengan bit awal 1111 1110 10 (FE80::/10)
- Site-Local Unicast Addresses dengan bit awal 1111 1110 11 (FEC0::/10)
- Multicast Addresses : dengan bit awal 1111 1111 (FF00::/8)
- ::8 diperuntukkan bagi pengalamatan yang belum di defenisikan
# Private address IPv6

Namun karena IPv6 cukup banyak tersedia, silakan pakai semua gan mencukupi
# NAT IPv4 ke IPv6
This document discusses issues with the specific form of IPv6-IPv4 protocol translation mechanism implemented by the Network Address Translator - Protocol Translator (NAT-PT) defined in RFC 2766. These issues are sufficiently serious that recommending RFC 2766 as a general purpose transition mechanism is no longer desirable, and this document recommends that the IETF should reclassify RFC 2766 from Proposed Standard to Historic status.
IPv6 The objections to NAT-PT include all the problems caused by NAT, but they're even worse, because ALGs can't simply rewrite addresses since IPv4 addresses and IPv6 addresses have different sizes. IPv6 hosts that use NAT-PT must have their DNS requests passed through an ALG that translates IPv4 addresses into special IPv6 addresses that are routed to the NAT-PT device that performs the translation.
It would of course be rather unpleasant if these specially-crafted DNS replies escape into the wild, where they would confuse IPv6 hosts that don't use the NAT-PT device in question, and dual stack hosts in particular. There are many other issues, such as timeouts, keepalives, incompatibility with DNSSEC and issues with authentication and encryption.
Pakai NAT Protocol Translator gan..

# Akses dari IPv6 ke IPv4
1. Perlu ditranslate dulu gan
2. PC/Server running dual stack (ipv4 dan ipv6)
