Looking for IPv6 MARTIAN prefix-set

I have this IPv4 MARTIANS list in use for filtering IPv4 BGP routes from ISPs:

prefix-set IPv4_MARTIANS
0.0.0.0/8,
10.0.0.0/8,
127.0.0.0/8,
169.254.0.0/16,
172.16.0.0/12,
192.0.2.0/24,
192.168.0.0/16,
240.0.0.0/4

I am looking for the equivalent in IPv6, possibly like this:

prefix-set IPv6_MARTIANS
::/0,
::/128,
::1/128,
::/96,
::ffff:0.0.0.0/96,
fe80::/10,
fec0::/10,
fc00::/7,
ff00::/8,
2001:db8::/32,
3ffe::/16

Hi @tmikelson ,

The following article discusses this topic:

https://6session.wordpress.com/2009/04/08/ipv6-martian-and-bogon-filters/

One comment tough about you IPv6 martian list. ::/0 (default route) is not a martian route. Filtering out ::/0 is probably not a good idea, unless you receive the full IPv6 Internet routing table from your service providers.
