Ok so I have a "new problem" attempting to use dhcp6c for BOTH IPv4 and IPv6. This is the salient part of the configuration file (the rest is basically defaults): # Generate SLAAC address using the Hardware Address of the interface #slaac hwaddr # OR generate Stable Private IPv6 Addresses based from the DUID #slaac private allowinterfaces igb0 #ipv6only #ipv4only # # Do not run these hooks; DO run the DDNS one in exit-hooks # nohook resolv.conf hostname ntp.conf interface igb0        ia_na 1        ia_pd 1/::/56 igb1/0/64 igb1.4/1/64 If I do "ipv6only" and run dhcpcd -T then I do get a prefix: root@IpGw:/usr/local/etc # dhcpcd -T dhcpcd-10.0.8 starting DUID 00:01:00:01:2e:3a:76:f1:00:0d:b9:46:71:88 igb0: IAID b9:46:71:88 igb0: IA type 3 IAID 00:00:00:01 igb0: IA type 25 IAID 00:00:00:01 igb0: soliciting a DHCPv6 lease igb1: activating for delegation igb1: IAID b9:46:71:89 igb1.4: activating for delegation igb1.4: IAID ff:00:00:04 igb0: soliciting an IPv6 router igb0: ADV 2600:6c5d:7009:600:c5e0:25ed:b364:36c2/128 from fe80::201:5cff:fe70:7c46 igb0: REPLY6 received from fe80::201:5cff:fe70:7c46 interface=igb0 pid=3395 protocol=dhcp6 reason=TEST skip_hooks='resolv.conf hostname ntp.conf' ifcarrier=up ifflags=34883 ifmetric=1001 ifmtu=1500 ifwireless=0 new_dhcp6_client_id=000100012e3a76f1000db9467188 new_dhcp6_domain_search=search.charter.net new_dhcp6_ia_na1_ia_addr1=2600:6c5d:7009:600:c5e0:25ed:b364:36c2 new_dhcp6_ia_na1_ia_addr1_pltime=3337 new_dhcp6_ia_na1_ia_addr1_vltime=3337 new_dhcp6_ia_na1_iaid=00000001 new_dhcp6_ia_na1_t1=1537 new_dhcp6_ia_na1_t2=2617 new_dhcp6_ia_pd1_iaid=00000001 new_dhcp6_ia_pd1_prefix1=2600:6c5d:5d00:9d00:: new_dhcp6_ia_pd1_prefix1_length=56 new_dhcp6_ia_pd1_prefix1_pltime=3337 new_dhcp6_ia_pd1_prefix1_vltime=3337 new_dhcp6_ia_pd1_t1=1537 new_dhcp6_ia_pd1_t2=2617 new_dhcp6_name_servers='2607:f428:ffff:ffff::1 2607:f428:ffff:ffff::2' new_dhcp6_server_id=000100012261b73d00144f9bcc84 dhcpcd exited This looks ok. That prefix is good and I presume if I let it set the other interfaces it will be ok. But if I do not say "ipv6only", leaving it that commented out so I can get both, I get on dhcpcd -T: root@IpGw:/usr/local/etc # dhcpcd -T dhcpcd-10.0.8 starting DUID 00:01:00:01:2e:3a:76:f1:00:0d:b9:46:71:88 igb0: IAID b9:46:71:88 igb0: IA type 3 IAID 00:00:00:01 igb0: IA type 25 IAID 00:00:00:01 igb0: soliciting a DHCPv6 lease igb1: activating for delegation igb1: IAID b9:46:71:89 igb1.4: activating for delegation igb1.4: IAID ff:00:00:04 igb0: rebinding lease of 71.15.253.203 igb0: leased 71.15.253.203 for 2813 seconds interface=igb0 pid=3358 protocol=dhcp reason=TEST skip_hooks='resolv.conf hostname ntp.conf' ifcarrier=up ifflags=34883 ifmetric=1001 ifmtu=1500 ifwireless=0 old_broadcast_address=255.255.255.255 old_dhcp_lease_time=3600 old_dhcp_message_type=5 old_dhcp_rebinding_time=3150 old_dhcp_renewal_time=1800 old_dhcp_server_identifier=96.33.192.1 old_domain_name_servers='71.10.216.1 71.10.216.2' old_interface_mtu=1500 old_ip_address=71.15.253.203 old_network_number=71.15.252.0 old_routers=71.15.252.1 old_subnet_cidr=22 old_subnet_mask=255.255.252.0 new_broadcast_address=255.255.255.255 new_dhcp_lease_time=2813 new_dhcp_message_type=5 new_dhcp_rebinding_time=2363 new_dhcp_renewal_time=1013 new_dhcp_server_identifier=96.33.192.1 new_domain_name_servers='71.10.216.1 71.10.216.2' new_interface_mtu=1500 new_ip_address=71.15.253.203 new_network_number=71.15.252.0 new_routers=71.15.252.1 new_subnet_cidr=22 new_subnet_mask=255.255.252.0 dhcpcd exited And if I actually boot the machine that way (rather than run it in test) I get only IpV4; the v6 solicitation never happens.
