DHCP Server Konfiguration für v6 testen:

dhcpd -6 -cf /etc/dhcp/dhcpd6.conf -t

DHCP Server Leases für v6 testen:

dhcpd -6 -cf /etc/dhcp/dhcpd6.conf -t

DHCP Server neu starten

service isc-dhcp-server restart

Sind DHCPv6 Server da?

ping -I enp0s3 ff02::1:2

DHCP Client für v6 testen: stateless (nur information, keine IP) Anfrage

dhclient -6 -S -v -sf /bin/true enp0s3

temporäte IPv6 Adresse anfordern:

dhclient -6 -T -v -sf /bin/true enp0s3

normale IPv6 Adresse anfordern:

dhclient -6 -N -v -sf /bin/true enp0s3

DORA (Dicover,Offer, Request, Ack) in IPv4 wird zu SARR (Silicit, Advertise, Request, Reply) in IPv6

• Lease heißt bei IPv6 Identity Assosiation
• IPv4 renew time heißt jetzt T1 (an den selben DHCP-Server)
• IPv4 rebind time heißt jetzt T2 (an alle DHCP-Server)

normale IPv6 Adressen von f00:0 bis fff:ffff: range6 2001:db8:0:910::f00:0 2001:db8:0:910::fff:ffff;

temporäre (nicht verlängerbare) IPv6 Adressen von 0 bis ffff: range6 2001:db8:0:910::/104 temporary;
