Summary
TelemaxX Telekommunikation
hosting isp business
64 prefixes, 145 neighbours, and a legacy /17 that belongs to a scientific instruments maker.
What it's used for
- A German data-centre and connectivity provider. 124,672 addresses across 64 IPv4 prefixes, thirteen IPv6 prefixes, and 145 observed BGP neighbours.
Notable
- The largest blocks are
149.236.128.0/17,149.236.64.0/18,149.236.32.0/19,85.115.0.0/19and213.144.0.0/19. - The three
149.236blocks all carry the netnameBAM-LAN, registered to a scientific instruments group, not to the announcing provider. - The provider's own netnames are
DE-TELEMAXX-19991206,20050224and20120410. - Nine of eighteen sampled addresses returned names; several different addresses answer with the identical name
customer.telemaxx.net.
Interesting
- A single legacy
/17,/18and/19registered to a manufacturer and announced by a hosting company is the classic shape of an outsourced enterprise. The instruments group kept the addresses it was allocated decades ago; the provider runs the network they sit on. - Multiple distinct addresses returning the same name,
customer.telemaxx.net, means the reverse zone answers with one placeholder for a whole range. It satisfies systems that insist an address have a name while telling an observer nothing, which is either tidy or evasive depending on why you are asking. 19991206uses the four-digit year. Another holder in this range is stamped991129, seven days earlier, in the two-digit form the registry abandoned. Between those two dates the convention changed, and both records still carry the version that was current the day they were filed.- 145 neighbours against 64 prefixes describes a carrier-neutral facility rather than a subscriber network. The business is being the place other networks connect, so interconnection count is the product.

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: 442 networks and 1,771 prefixes, as published 2026-10-15. 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.
