New ZealandRegistryAPNICTypeCarrier

As of 14th November 2026, AS4648 (Spark New Zealand), a transit carrier registered in New Zealand with APNIC, originates 165 IPv4 prefixes covering 78.8k addresses and 5 IPv6 prefixes. By IPv4 address space that makes it the 2,864th-largest of the 80,840 networks we see originating IPv4, and the 12th-largest of 421 in New Zealand. It is seen behind 30 upstream networks, most often AS1299 (Arelion (fka. Telia Carrier)) and AS2914 (NTT America, Inc.), and in front of 48 downstream networks. 11% of its announcements have a valid RPKI ROA, and none are RPKI-invalid. Over 99% of its routes reach at least 90% of full-feed peers, and 1 prefix is also originated by another network.

Upstream graph

The networks AS4648 is seen behind, one and two hops out, drawn from real AS paths.

Networks observed one and two hops upstream of AS4648 in real AS paths. A thicker line means more vantage points saw that adjacency, so weight tracks how well attested it is — not how much traffic it carries. Adjacency is an observation; whether it is a transit purchase or a settlement-free peering is an inference, and is labelled as one wherever we show it.
