Check https://github.com/job/aggregate6 (thank you, Job)
Marco Marzetti (PCCW) wrote an even faster compression tool! https://github.com/lamehost/aggregate-prefixes Both these python implementations are meant as replacements for ISC's vintage 'aggregate' Unix utility, with the notable difference that they also support IPv6. Example: job@bench ~$ pip3 install aggregate-prefix job@bench ~$ wc -l dfz_ipv4 810607 job@bench ~$ cat dfz_ipv4 | time aggregate-prefixes - | wc -l 141645 1m40.17s real 1m37.39s user 0m01.60s system Compressing the whole IPv4 DFZ prefix list takes only 100 seconds. Kind regards, Job
