I'm running OpenBSD, or maybe FreeBSD.  I don't have lots of IPv4 addresses to waste, but who doesn't have a few billion of IPv6 ones?How do I add some extra IPv6 hops to a traceroute6, around pf(4) on OpenBSD?Similar to how Ryan Werber of Beagle Networks did it:# traceroute -f2 -m255 -q1 -w2 obiwan.scrye.nettraceroute to obiwan.scrye.net (204.244.252.35), 255 hops max, 40 byte packetsSkipping 1 intermediate hops 2  hos-tr1.juniper1.rz13.hetzner.de (213.239.224.1)  0.224 ms 3  core22.hetzner.de (213.239.245.121)  1.115 ms 4  core1.hetzner.de (213.239.245.177)  4.802 ms 5  core1.hetzner.de (213.239.245.177)  4.836 ms 6  juniper1.ffm.hetzner.de (213.239.245.5)  5.366 ms 7  10gigabitethernet1-4.core1.lon1.he.net (72.52.92.81)  22.797 ms 8  10gigabitethernet10-4.core1.nyc4.he.net (72.52.92.241)  112.799 ms 9  10gigabitethernet10-4.core1.nyc4.he.net (72.52.92.241)  148.894 ms10  100gigabitethernet7-2.core1.chi1.he.net (184.105.223.161)  109.669 ms11  100ge9-1.core1.sea1.he.net (184.105.223.193)  157.816 ms12  10ge1-1.core1.yvr1.he.net (184.105.222.2)  176.844 ms13  10ge1-1.core1.yvr1.he.net (184.105.222.2)  160.813 ms14  216.218.185.138 (216.218.185.138)  215.201 ms15  gi4-0-528.bbr3.yyz.epikip.net (206.214.255.9)  152.165 ms16  216.81.55.118.epikip.net (216.81.55.118)  195.530 ms17  216.81.55.118.epikip.net (216.81.55.118)  167.154 ms18  206.214.251.27 (206.214.251.27)  186.840 ms19  A.NEW.HOPE (206.214.251.6)  208.222 ms20  It.is.a.period.of.civil.war (206.214.251.9)  171.58 ms21  It.is.a.period.of.civil.war (206.214.251.9)  184.470 ms22  Rebel.spaceships (206.214.251.14)  178.100 ms23  have.won.their.first.victory (206.214.251.22)  158.662 ms24  against.the.evil.Galactic.Empire (206.214.251.25)  203.261 ms25  against.the.evil.Galactic.Empire (206.214.251.25)  177.668 ms26  During.the.battle (206.214.251.30)  172.850 ms27  to.steal.secret.plans (206.214.251.38)  203.746 ms...
