AS13684 — ASN-MEDTRONIC-1

AS13684 announces 3 IPv4 prefixes covering 66,816 addresses and 1 IPv6 prefixes.

About this network

One /16 announced as thirty-five separate pieces, and a pair of IPv6 blocks at a prefix length almost nobody uses.

What it's used for

• A medical device manufacturer's network. 66,816 addresses across thirty-five IPv4 prefixes, two IPv6 blocks, and ten observed BGP neighbours.

Notable

• Nearly every IPv4 prefix sits inside 144.15, and all of them share the single netname MEDTRONIC.
• The pieces range from /19 down to /24 and are announced separately rather than as the whole.
• The IPv6 blocks are 2620:14a::/37 and 2620:14a:800::/37, an uncommon prefix length, and the two sit adjacent.
• Eighteen addresses were queried for reverse DNS and none returned a name.

Interesting

• Splitting one allocation into thirty-five announcements is usually traffic engineering: different pieces leaving through different providers, with ten neighbours available to steer between. The cost lands on every router that carries the entries.
• Two adjacent blocks at the same odd prefix length are one larger block split down the middle, kept as two objects rather than one so each half can be routed on its own.
• A manufacturer of implantable devices publishing nothing in reverse DNS across sixty-six thousand addresses is consistent from the first block to the last, and the quietest large estate in this range of the routing table.
