isp telecom infrastructure

Thirty years of address allocations, each one dated in its own netname, starting in 1989.

What it's used for

  • The telecoms arm of a German energy utility, serving business and residential customers. 163,584 addresses across 32 IPv4 prefixes, four IPv6 prefixes, and 155 observed BGP neighbours.

Notable

  • Almost every block is named DE-HEAGMEDIANET- followed by a date: 19890522, 19930901, 19971008, 19990511, 20000104, 20020123, 20021209, 20041207, 20080605, 20100317 and 20121106.
  • 134.101.16.0/20 carries the 1989 date, the oldest seen in this range.
  • 141.187.0.0/16 is registered to a semiconductor company under the netname FMG-FML.
  • Twelve of eighteen sampled addresses returned names, all of the form IP-085132200000.dynamic.medianet-world.de.

Interesting

  • This one record is a thirty-year allocation history. Each netname carries the date the block was registered, so the sequence reads as a company growing in steps: a block in 1989, another four years later, then roughly every two or three years through 2012. Most networks give you a snapshot. This one gives you the whole timeline.
  • The 1989 date predates the registry that now holds the record and predates commercial internet service in Germany. Blocks like this were handed out to research and utility networks and simply carried forward, which is why a modern regional ISP holds address space older than its business.
  • A /16 named after a semiconductor manufacturer sits in the middle of the inventory. Legacy blocks move between companies far more often than their registry records get rewritten.
  • The reverse names pad every octet to three digits, so hostnames sort correctly as plain text.

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: 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.
