AS14657 announces 1 IPv4 prefixes covering 256 addresses and 0 IPv6 prefixes.

About this network

Every part of the address is padded to three digits in the reverse DNS.

What it's used for

• A lift truck manufacturer's network. 256 addresses in a single IPv4 prefix, with two observed BGP neighbours and no IPv6 announced.

Notable

• All three sampled addresses answer as syn-071-067-058-064.biz.spectrum.com and similar, with leading zeroes on every part.
• The whole footprint is 71.67.58.0/24, carrying the netname CROWN-EQUIPMENT-CORP and registered to the company.
• The AS handle contracts the same name to three initials and a suffix.
• Three addresses were queried for reverse DNS and all three returned a name.

Interesting

• Zero-padding makes every hostname the same length, which means they sort in numeric order when sorted as text. That is a convenience for whoever generates and greps the zone, and it produces names that no human would type from an address without checking.
• The netname spells the company out in full while the handle cuts it to initials, so the record holds the longest and shortest forms of the same name side by side.
• The block is registered to the manufacturer even though the reverse DNS is entirely the carrier's, which is the reverse of the usual arrangement in this range.
• Two upstreams supports a manufacturer whose dealers and service network reach central systems through them.
