isp residential cable dsl

MCM-AS-ID is operated by PT. Mandiri Citra Makmur.

What it's used for

  • The address space carries internet access traffic, evidenced by reverse DNS entries such as ip-135-177-255.mcm-id.net and netnames MCM-ID registered to PT. Mandiri Citra Makmur.
  • The AS announces 2048 IPv4 addresses across 3 prefixes and maintains 4 observed neighbours, a ratio consistent with an access network serving local subscribers rather than a transit provider.
  • As an Internet Service Provider offering cable and DSL solutions, the traffic consists of residential and small business subscriber eyeballs accessing the internet.

Notable

  • All registrants for the announced prefixes agree with the announcer, listing PT. Mandiri Citra Makmur under the netname MCM-ID.
  • The address inventory is compact, consisting of three contiguous IPv4 blocks within the 203.135.0.0/16 range.

Classification and threat

Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.

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: 431 networks and 1,768 prefixes, as published 2026-10-12. 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.
