`30:T46d,md` Parameters avilable in this notebook: af address family. date date to fetch the data for, in YYYY-MM-DD format. origin origin, can be an ASN or an IX-ID (as in PeeringDB, for example "ix-26" for AMS-IX). network origin, can be an ASN or an IX-ID (as in PeeringDB, for example "ix-26" for AMS-IX). protocol Measurement protocol to filter for. Options are: icmp, tcp, udp.
