About this network

Five blocks carry the same registry code with one more letter of the company name in front each time.

What it's used for

• A regional ISP's network in Canada. 4,096 addresses across nine IPv4 prefixes, with two observed BGP neighbours and no IPv6 announced.

Notable

• Five netnames are the same code with a growing prefix of the company name, each adding one letter: 15-04313-210300-21-20160209-CA, SEC15-04313-210300-21-20160209-CA, SECU15-04313-210300-21-20160209-CA, SECUR15-04313-210300-21-20160209-CA and SECURE15-04313-210300-21-20160209-CA.
• Two blocks belong to other companies: TUG-NET registered to Tugnet Enr, and VANTREE-COM registered to VanTree Systems Inc.
• Six of eighteen sampled addresses answered, including mtl-pppoe-adsl763.securenet.net, tnt1-mtl-dialup123.securenet.net, dialup128.efsnet.ca, and three addresses all returning ns1432.ztomy.com.

Interesting

• The growing prefix is a collision workaround. Netnames must be unique within the registry, the code was the same on every filing, and the fix each time was to add one more character of the company name until the string was free. Five filings, five letters, in order.
• The reverse zone is a museum. It names dial-up concentrators by number and site, marks other addresses as broadband over telephone line, and does both in a city abbreviation that predates everything else here. Those names survive because deleting them is work and leaving them is not.
• Three addresses answering with the same nameserver hostname belong to a domain-parking operation, which is what a block ends up doing when the customers who used it have gone.
• Two acquired ISPs kept their own registry records, so the company's history is legible from its netnames alone.
