About this network

One block, one answer, and that answer names a cache.

What it's used for

• A company network. A single IPv4 /22 announced from the United States, no IPv6, and one observed BGP neighbour.

Notable

• The block is registered under the netname ETRN-MKC-NET1, with a registrant field holding three entries joined by semicolons: the company plus an abuse desk and a network operations centre.
• One of three sampled addresses answered, with c-dnscache-mkc1.etrn.com.
• That name declares the host's function and carries the same three-letter site code that appears in the AS handle and in the netname.
• The AS handle is ETRN-MKC, so handle, netname and reverse name all agree on the site.

Interesting

• Two role desks sitting in the registrant field is a field-shape problem rather than an ownership one. Abuse and operations contacts belong in their own contact records, and joining them into the organisation field means anything reading that field as a company name gets three of them.
• The reverse name is unusually informative for a single answer. It says what the machine does, which site it lives at, and that there is expected to be more than one of it. That is three facts volunteered where most records in this range volunteer none.
• One upstream and one block, with the same site code repeated in every identifier, reads as a single-location network that has never needed a second.
