There is also the problem noted by Wes George with 6to4 being used in DNS amplification, which may be interesting.. http://iepg.org/2018-03-18-ietf101/wes.pdf
I configure my DNS servers with a long-ish list of bogon addresses. For v6, the list includes Teredo and 6to4 and various other horrors: # RFC 5156 and IANA IPv6 address space registry server 0000::/3 { bogus yes; }; server 2001:0000::/32 { bogus yes; }; server 2001:0002::/48 { bogus yes; }; server 2001:0010::/28 { bogus yes; }; server 2001:0db8::/32 { bogus yes; }; server 2002::/16 { bogus yes; }; server 3000::/4 { bogus yes; }; server 4000::/2 { bogus yes; }; server 8000::/1 { bogus yes; }; Tony. -- f.anthony.n.finch <dot () dotat at> http://dotat.at/ Southeast Iceland: Cyclonic, mainly westerly, 6 to gale 8, decreasing 5 later. Rough or very rough, becoming moderate or rough later. Showers. Moderate or good.
