AS13607 — INTUITIVE-ENG

AS13607 announces 5 IPv4 prefixes covering 2,304 addresses and 3 IPv6 prefixes.

About this network

One block is netname SPRINTLINK, a carrier's product name standing in for the customer's.

What it's used for

• A surgical robotics manufacturer's network. 2,304 addresses across five IPv4 prefixes, three IPv6 prefixes, and three observed BGP neighbours.

Notable

• 199.87.76.0/22 is netname INTUITIVE-ENG-DC, ending in initials for a data centre.
• Three blocks share netname IS-14, two letters and a counter.
• 65.160.57.0/24 is netname SPRINTLINK, registrant Intuitive Surgical; hostmaster.
• The three IPv6 blocks are all /48s from one range, at widely spaced offsets.
• Fifteen addresses were queried for reverse DNS and none returned a name.

Interesting

• A netname that is a carrier's retired backbone brand tells you the block was cut from that carrier's space and labelled by its provisioning system, which never asked what the customer was called.
• Appending a role rather than a team name after the semicolon is unusual. Most such records name a department; this one names the mailbox, which is what the registry actually wanted in the first place.
• Three /48s at scattered offsets inside one range, rather than one shorter prefix, is a company handing out standard-sized site allocations from its own pool and announcing only the ones in use.
