About this network

Thirty-one prefixes, one netname, and it is an acronym for something else.

What it's used for

• A rural fibre provider's network. Thirty-one IPv4 prefixes announced from the United States, no IPv6, and three observed BGP neighbours.

Notable

• Nearly every block carries the netname TEPA-4, a four-letter acronym followed by the protocol version, which shares no letters in sequence with the holder's name.
• One block breaks the pattern with a netname that spells the company out and adds a counter, so the two conventions sit side by side in the same record.
• Eighteen addresses were queried for reverse DNS and none returned a name.
• The routing history begins in 2004, well before the fibre business the holder is named for.
• Thirty-one separate announcements cover thirty-seven thousand addresses, an average of about twelve hundred each.

Interesting

• An acronym that cannot be derived from the current company name almost always preserves the organisation that first received the addresses. The registry keeps the old identity because renaming a netname means reissuing it, and nobody does that for a label nobody reads.
• Thirty-one announcements for a network this size means the space arrived in many small pieces over many years rather than as one allocation, which is the normal shape for a provider that grew by serving one community at a time.
• No reverse names at all across a whole subscriber network is a choice, and it means an address here carries no clue about which town or device it belongs to.
