AS12843 — TELEMAXX

AS12843 announces 49 IPv4 prefixes covering 124,672 addresses and 13 IPv6 prefixes.

About this network

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, 85.115.0.0/19 and 213.144.0.0/19.
• The three 149.236 blocks all carry the netname BAM-LAN, registered to a scientific instruments group, not to the announcing provider.
• The provider's own netnames are DE-TELEMAXX-19991206, 20050224 and 20120410.
• Nine of eighteen sampled addresses returned names; several different addresses answer with the identical name customer.telemaxx.net.

Interesting

• A single legacy /17, /18 and /19 registered 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.
• 19991206 uses the four-digit year. Another holder in this range is stamped 991129, 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.
