AS15735 — DATASTREAM-NET

AS15735 announces 29 IPv4 prefixes covering 181,760 addresses and 3 IPv6 prefixes.

About this network

The netnames publish the product line, and two of them carry a date with a sequence number attached.

What it's used for

• The national telecoms operator. Eighty-nine IPv4 prefixes and three IPv6 prefixes announced from Malta, one hundred and eighty-one thousand addresses, across thirteen observed BGP neighbours.

Notable

• Several netnames spell out which product the block serves: a country code, the brand or a product tier, then words for mobile, retail and subscriber line access, then an allocation date.
• Two of those dates run to ten digits rather than eight, with a two-digit counter after the day, so more than one block was filed on the same date and the field had to distinguish them.
• One product-line netname carries a former brand that the company no longer trades under.
• The product-line blocks list only a hostmaster object. The plainly named ones list the company as well, so the naming convention and the contact set move together.
• The three IPv6 announcements are all /48 pieces of one range, not the allocation itself.
• Eighteen addresses were queried for reverse DNS and none returned a name.

Interesting

• A date field that overflowed into a counter is a registry being used as an inventory system. The same day appears twice, so a sequence number was appended, and the netname stopped being a name.
• Naming the product in the address record tells anyone reading the routing table which blocks hold home subscribers and which hold anything else.
