Thanks

Max

Their communities are also documented in their own IRR:

$ whois -h rr.level3.net -- '-s LEVEL3 AS3356'

That aut-num object seems to be more up-to-date than the one in
RIPE-NONAUTH:

aut-num: AS3356
...
source: RIPE-NONAUTH
last-modified: 2023-11-28T20:03:20Z

in contrast to:

aut-num: AS3356
...
source: LEVEL3

Kind regards,

Job
