AS13833 — ASN-NOS

AS13833 announces 2 IPv4 prefixes covering 512 addresses and 0 IPv6 prefixes.

About this network

Both netnames pack an address into digits with the dots removed, and the two come out different lengths.

What it's used for

• A telecommunications company's network. 512 addresses across two IPv4 prefixes, two observed BGP neighbours, and no IPv6 announced.

Notable

• 70.103.75.0/24 is netname ELI-6323-70103750, three letters, an AS number, and the address with its separators stripped.
• 70.103.230.0/24 is netname ELI-6323-701032300 by the same rule, one digit longer.
• Both are registered to the same company; the first record also names an address administration contact.
• 70.103.75.64 answers as message.textmorse.com, a domain matching neither the company nor the netnames.

Interesting

• Stripping the dots out of an address makes the result impossible to read back. The two strings differ in length because one octet has three digits and the other has two, so nothing short of trying every split recovers the original. Padding each octet would have cost two characters and kept the label reversible.
• The four-digit number sitting between the letters and the address is another network's number, which dates the assignment to whoever held the space before this company did.
