May I please solicit some comments about Abuse Block lists (Without detracting from RFC 5782 and RFC 6471 or : https://www.ripe.net/publications/docs/ripe-409 ) Considering that DNSBL tech is "MOSTLY" "reactive" (after he abuse) - although - there are - some - DNSBL (apparently Spamhaus? etc etc) that apparently block before anything happens (thank you for pointing this out Simon) The block time policies of RBLs - Not specifically anyone blocklist in particular - just the general policies) *********************************** Among the reactive and pre emptive DNSBL, there are two main types of block lists: No automatic removal and automatic removal Is the policy to auto de-list after a period of time, still accurate? or should block lists not auto de list at all any longer? If still auto de-list - Considering the change in abuse patterns and technology, should the block times be increased or de-creased? Then; Ignoring pre-emptive - predictive (in advance for no reason) blocking: Does society require more specialist non auto de-list DNSBLs? (Would it be helpful to civil society, law enforcement etc to have a "child pornography" dnsbl? or a phish dnsbl? - or is the reactive time to high in order for dynamic ipv4? - but on ipv6 allocations to devices could be more 'permanent'? etc) Andre
