To Whom It May Concern: (Cc'ed [EMAIL PROTECTED])
Usually i prefer 6to4(stf(4)) to 6over4(gif(4)) because some
tunnel providers like to limit bandwidth too musch. So until my
upstream ISP give me native ipv6 addresses (it's take long time maybe),
i'm going to use 6to4 instead of 6over4 continuous.
Here is my shot using 6to4:

And from now on, i would give you one question. Why is 7.0-BETA1
different from another -RELEASE in hostname resolving order? AFAIK, at
least on 6.2-RELEASE, the order is first IPv6 and then IPv4. However,
7.0-BETA1 try to lookup in first IPv4 than IPv6. Here is the evidence:
[EMAIL PROTECTED]:~> uname -srm
FreeBSD 6.2-RELEASE-p8 i386
[EMAIL PROTECTED]:~> telnet mx.jp.freebsd.org 25
Trying 2001:218:422:1::15...
Connected to mx.jp.freebsd.org.
Escape character is '^]'.
[......]
[EMAIL PROTECTED]:~> ssh -v mx.jp.freebsd.org.
debug1: Connecting to mx.jp.freebsd.org. [2001:218:422:1::15]
^C
And
[EMAIL PROTECTED]:~> uname -srm
FreeBSD 7.0-BETA1 i386
[EMAIL PROTECTED]:~> telnet mx.jp.freebsd.org 25
Trying 210.226.20.15...
Connected to mx.jp.freebsd.org.
Escape character is '^]'.
[......]
[EMAIL PROTECTED]:~> ssh -v mx.jp.freebsd.org.
debug1: Connecting to mx.jp.freebsd.org. [210.226.20.15]
^C
What happended? Is there anyone to dislike IPv6 in src committers?
Please let me know the correct answer to this puzzle ;;
