Summary
DOKOM Gesellschaft fuer Telekommunikation
isp telecom business hosting
One netname carries an allocation date of DE-MKNET-19840101, older than almost anything else here.
What it's used for
- A regional operator's network. Sixty-three IPv4 prefixes and one IPv6
/32announced from Germany, ninety-two thousand one hundred and sixty addresses, across a hundred and thirty-eight observed BGP neighbours.
Notable
- The dated netnames run
DE-MKNET-19840101,DE-MKNET-990308andDE-MKNET-20050405, so one holder shows an eight-digit date, a six-digit date and the changeover between them. - The first of those reads as the first day of nineteen eighty-four, which predates the registry that now holds the record.
- The four letters in the middle of every dated netname are not the brand in the holder string.
- One block is a dynamic pool whose netname ends in a code naming a site and a piece of equipment.
- Two blocks belong to other companies outright: a logistics firm and a media and communications firm, each with its own hostmaster.
- Eighteen addresses were queried and all eighteen returned a name, every one the four octets hyphenated under a brand domain with a two-digit suffix the holder string does not have.
Interesting
- Addresses ending in zero and in two hundred and fifty-five answer with names of exactly the same shape as the ones in between. The zone is generated for every address, whether or not one can be used.
- A brand with a number attached in the reverse names and in the hostmaster, but not in the company name, is a rebrand that reached operations before it reached the registry.

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 1,775 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.
