About this network

A netname cut one character short, so a prefix length reads as a digit.

What it's used for

• A satellite connectivity provider's network. Eleven IPv4 blocks announced from the United States, no IPv6, and five observed BGP neighbours.

Notable

• The largest block carries the netname NET-64-40-160-0-2, which is the address followed by a prefix length missing its final character.
• Five netname styles appear across eight blocks held by this operator: the truncated address form, X2NSAT-FNS, IPA-X2NSAT-01, XNSAT-216-245-243-0 and XNSAT-216-245-246-0.
• Two of those drop the digit out of the company name, so X2NSAT and XNSAT both appear as the same operator's abbreviation.
• Three further blocks are registered to a different satellite operator entirely, under the netname VIASAT.
• Twelve of eighteen sampled addresses answered, all in the form 104-171-98-0.x2nsat.com.

Interesting

• The truncated netname is the kind of defect that survives forever. It still looks like a valid identifier, so nothing flags it, and anyone reading the block size out of the netname will be off by an order of magnitude.
• Dropping a digit that is part of the company name produces two strings that both look correct. Matching this operator's space by name requires knowing both.
• Announcing another satellite operator's blocks alongside its own is the ordinary shape for a reseller or a partner arrangement, and it is only visible in the registry, never in the routing.
