AS15034 TIBA S.A.

Every sampled address, across five blocks, answers with the same name.

What it's used for

• An internet provider's network. Seven IPv4 blocks announced from Argentina, no IPv6, and five observed BGP neighbours.

Notable

• All eighteen sampled addresses returned a reverse name, and every one of them was the identical string free-host.tiba.com.ar.
• The netname on all seven blocks is not a name at all but an address range, written as 200.61.64.0 and 200.61.127.255 separated by a spaced hyphen.
• That range is the parent the seven announced blocks are cut from, so every block is labelled with the whole rather than with itself.
• The holder record uses the AS number itself as the handle, while the AS handle field holds the company name including its punctuation.

Interesting

• One name for every address is a wildcard reverse zone, and it makes the reverse lookup carry no information. Anything that resolves an address here to identify a host learns only that the address belongs to this operator, which is what the routing already said.
• The word in that name suggests unassigned or unbilled space, published uniformly rather than per customer.
• Putting the parent range in every netname is the opposite failure from the usual one. Most bare address netnames at least describe their own block; these describe a range sixty-four times larger than some of the blocks carrying it.
• A company name with a space and a period in a handle field is unusual, since handles are normally restricted to a compact character set.
