<p>I didn't see any replies to this message, but here is my ifconfig
regarding l0:</p>
<p>lo0: flags=8049<UP,LOOPBACK,RUNNING,MULTICAST> metric 0 mtu
16384<br>
options=680003<RXCSUM,TXCSUM,LINKSTATE,RXCSUM_IPV6,TXCSUM_IPV6><br>
inet 127.0.0.1 netmask 0xff000000<br>
groups: lo<br>
</p>
<p>I turned off IPV6 option in the kernel and rebuilt it.</p>
<p><br>
</p>
<p>It was an interesting process. It seems to break some ports.</p>

seem to figure out how to completely disable ipv6 in 12.4-RELEASE.
<br>
Tried everything I've found in searches, I think.
<br>
<br>
rc.conf:
<br>
<br>
ip6addrctl_enable="NO"
<br>
ip6addrctl_prefer_ipv4="YES"
<br>
ip6addrctl_prefer_ipv6="NO"
<br>
ipv6_activate_all_interfaces="NO"
<br>
# neither of the 2 lines below have any effect;
<br>
# nor does the absence of them
<br>
# lo0 always has ipv6 configured
<br>
#ipv6_network_interfaces="none"
<br>
#ipv6_network_interfaces=""
<br>
<br>
An ifconfig shows no ipv6 on any interfaces except lo0:
<br>
<br>
lo0: flags=8049<UP,LOOPBACK,RUNNING,MULTICAST> metric 0 mtu
16384
<br>
options=680003<RXCSUM,TXCSUM,LINKSTATE,RXCSUM_IPV6,TXCSUM_IPV6>
<br>
inet6 ::1 prefixlen 128
<br>
inet6 fe80::1%lo0 prefixlen 64 scopeid 0x3
<br>
inet 127.0.0.1 netmask 0xff000000
<br>
groups: lo
<br>
nd6 options=21<PERFORMNUD,AUTO_LINKLOCAL>
<br>
<br>
So how do I get rid of it on lo0?
<br>
Should I care?
<br>
