About this network

Reverse names that write the address backwards and keep the dots.

What it's used for

• A regional provider's network. Three IPv4 prefixes and one IPv6 /32 announced from the United States, with three observed BGP neighbours.

Notable

• Four of nine sampled addresses answered. Three take the form ip-64.166.232.198.sbbsnet.net: the final octet as a label, then the remaining three octets in reverse order with their dots intact.
• The fourth adds a customer name as an extra label between the reversed address and the domain, and prefixes the whole thing with words for network and customer.
• The three blocks carry three unrelated netnames: one built from the operator's own short name, and two that are ordinary words with no connection to it or to each other.
• Every block is registered to the holder despite those names.

Interesting

• Keeping the dots while reversing the octets is the worst of both conventions. The name is four labels deep for no structural reason, and reading the address out of it requires knowing to reverse the middle three parts but not the first.
• Two netnames that are just words are a reminder that this field has no rules. They were meaningful to whoever typed them and carry nothing an outsider can use, which is more honest than the netnames that encode an address and then go stale.
• Naming the customer in the reverse zone tells anyone sampling the space which addresses belong to which business, without a single query reaching the provider.
