isp residential cable dsl

BLAMBANGAN-AS-ID is operated by PT Blambangan Cahaya Timur.

What it's used for

  • The address space carries residential broadband traffic, as indicated by the netname BLAMBANGANNET-ID and the registrant IRT-BLAMBANGANNET-ID.
  • The AS announces 1024 IPv4 addresses across a single prefix (103.224.64.0/22) and maintains 3 observed neighbours, a ratio consistent with a local access provider rather than a transit hub.
  • Traffic consists of subscriber eyeballs for cable and DSL services in the Blambangan region of East Java.

Notable

  • The RDAP registrant IRT-BLAMBANGANNET-ID aligns with the AS holder PT Blambangan Cahaya Timur, confirming consistent ownership of the address space.
  • The inventory is compact, consisting of a single /22 block with no IPv6 prefixes announced.

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.
