isp residential cable dsl

DOT is operated by DOTRO Telecom.

What it's used for

  • The address space carries residential and business internet access, evidenced by netnames such as RO-DOTROTELECOM-20050418 and DOTRO-TELECOM-Business.
  • The AS announces 3,840 IPv4 addresses across 8 prefixes and 3 IPv6 prefixes, with 14 observed neighbours, indicating a regional access provider role.
  • Traffic consists of subscriber eyeballs for cable and DSL services in Romania, as identified by PeeringDB as a Cable/DSL/ISP.

Notable

  • Registrants for the majority of prefixes are DOTRO Telecom NOC and DOTRO TELECOM SRL, aligning with the AS holder.
  • One prefix, 154.46.31.0/24, is registered to Cogent Communications, LLC with netname COGENT-154-46-16, suggesting leased or transit space rather than native DOTRO infrastructure.
  • The inventory includes a mix of /22, /23, and /24 blocks, with the largest being 86.104.176.0/22 and 185.163.104.0/22.

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 1,775 prefixes, as published 2026-10-11. 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.
