About this network

The registry credits one company; the hostnames credit another.

What it's used for

• A rural telephone company's network. 2,048 addresses in a single IPv4 prefix, with one observed BGP neighbour and no IPv6 announced.

Notable

• 104.244.144.0/21 carries the netname USTC, matching the telephone company, but the registrant is ROPIR INDUSTRIES.
• One of three sampled addresses answered, with host-104-244-149-254.ustconline.net.
• The AS first appeared in routing on 2000-08-18.

Interesting

• Netname and registrant disagreeing is the fingerprint of a company that changed hands or restructured and updated exactly one field. The netname is the abbreviation of the operating telephone company, the registrant is a holding entity, and the reverse DNS is the customer-facing brand. Three different answers to who owns these addresses, all correct.
• Working out who to contact about an address means checking all three, which is why abuse handling is harder than it sounds and why registries ask for role contacts rather than company names.
• The block is from recent space rather than the range this company would have been given in the era its AS number implies, so the original allocation is gone and this one was bought or transferred.
• A single upstream and a single block is a small operator that has kept its own routing rather than disappearing into a larger network, which for a rural telephone company is a choice about independence.
