At which IPv6 stage are you? Scared The address is too long! All my IP addresses are traceable! Angry It's a conspiriacy there is no IPv4 shortage! As long as I get an IPv4 address I don't care! Nobody is using it anyway! Confused

There are so many new acronyms. SLAAC, DAD, RA, ND ... Why can't I reach IPv6 websites over IPv4? Why are multiple IPv6 address assigned to interfaces?

Confused Confused

My home network is running on IPv6. I know what SLAAC, RD and ND are. I can classify IPv6 addresses. I can configure an IPv6 firewall.

IPv6 Status

Umstellungsphase Alle Kunden erhalten die gleiche Anzahl IPv6-Adressen gemäss Zuteilung im IPv4-Adressraum, um die Dual-Stack-Implementation (Parallelbetrieb) sicherstellen zu können. Die Zuweisung erfolgt ohne zusätzlichen Kosten. Bestehende Kunden können die Zuteilung via Support System jederzeit anfragen. Diese Phase dauert an bis die METANET IPv4-Allokation ausgeschöpft ist. Post-Transitionsphase Neue Systeme erhalten ab diesem Zeitpunkt nur noch IPv6-

  • Adressen. Dies wird voraussichtlich nicht vor 2016 der Fall sein.

There are so many new acronyms.

SLAAC

StateLess Address AutoConfiguration.

Unlike DHCP in IPv4 the host portion of the IPv6 address is independently determined by the host itself.

DAD

Duplicate Address Detection

Ensures there is no other Host on the same broadcast domain.

ND

Neighbor Discovery Protocol

Used for getting information about the network neighborhood, somwhat similar to ARP.

RA

Router Advertisement

Part of the NDP. Sent by a router to annouce a gateway to into the subnet.
