isp residential legacy

AS9922 (NKB-AS-TW) is held by New Kaohsiung Broadband Ltd., a broadband operator registered in Lingya District, Kaohsiung, Taiwan, and listed in PeeringDB as a cable/DSL access network. It is a regional access provider rather than a carrier: it buys transit rather than selling it, and its space is filled with consumer subscriber lines.

What it's used for

Residential internet access. RIS observes 162 IPv4 prefixes carrying 51,456 addresses, no IPv6, and 10 BGP neighbours. Read together those numbers fix the role. Fifty thousand addresses is a substantial subscriber pool, but ten adjacencies is far too few for a wholesale business: a carrier reselling that space would live on peering breadth and show hundreds of neighbours. Ten is what an access ISP has, a couple of transit upstreams plus a few local peers to reach the rest of the Taiwanese internet.

The prefixes come from a handful of parent ranges (39.1, 61.61, 106.105, 124.218, 203.190) deaggregated hard, the same blocks appearing as /19s through /22s at once, which is how an access ISP splits pools per region and per access technology.

The reverse DNS makes the subscriber mix explicit. Addresses in 124.218 resolve as 124-218-64-5.cm.dynamic.apol.com.tw, cm for cable modem and dynamic for a DHCP pool, under apol.com.tw. Addresses in 39.1 resolve as 39-1-0-5-adsl-KHH.dynamic.so-net.net.tw, ADSL lines tagged with the city, under so-net.net.tw. One ASN carries eyeballs presented under at least two consumer brands on two last-mile technologies. That shows what the space carries, not who holds it.

Notable

  • The city codes in the DSL names (KHH Kaohsiung, TPE Taipei) show the footprint reaches beyond Kaohsiung.
  • Dynamic pools dominate the sample, so geolocation against this ASN should be treated as coarse.

Classification and threat

Residential Fixed-line consumer ISP. Addresses here are homes.

Spamhaus DROP

Not on ASN-DROP The network as a whole is not listed.

No DROP prefixes None of its announced space is on the DROP prefix list.

Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 442 networks and 1,773 prefixes, as published 2026-10-13. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.

FBI IC3

No IC3 indicators Nothing from the FBI IC3 feed.

IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
