Summary
ith Kommunikationstechnik
isp telecom business
The AS handle is a street, a house number, a postcode and a town.
What it's used for
- A communications company's network. Twenty-seven IPv4 prefixes announced from Germany, no IPv6, sixteen thousand eight hundred and ninety-six addresses, across one hundred and seven observed BGP neighbours.
Notable
- The handle carries the brand and then a full postal address, including a country letter joined to the postcode by a hyphen.
- Most blocks share one netname of a country code, the brand and the date
20041119, so a large batch was registered on a single day. - One older block carries a date four years earlier, and two carry only the brand with the three letters for a network, with an abuse role as their sole registrant.
- The company writes its own brand in lower case in the registrant field and in capitals everywhere else.
- Twenty-seven announcements cover two ranges, split down to
/24s in places while the surrounding space is announced whole. - Eighteen addresses were queried for reverse DNS and none returned a name.
Interesting
- One hundred and seven neighbours against sixteen thousand addresses is the ratio of a network that peers rather than buys. The addresses are almost incidental; what this number is for is being present at exchanges.
- A postal address in a handle dates from when the registry doubled as a phone book, and it has outlived every system that would have used it.

Reputation
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: 446 networks and 1,852 prefixes, as published 2026-10-27. 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.
