AS13319 — S-I-S

Network type: residential

AS13319 announces 9 IPv4 prefixes covering 16,896 addresses and 1 IPv6 prefixes.

About this network

Two generations of reverse-name scheme, distinguished by which end of the hostname the label sits on.

What it's used for

• A Canadian internet service provider. 17,152 addresses across twenty-three IPv4 prefixes, fourteen IPv6 prefixes, and twelve observed BGP neighbours.

Notable

• Older blocks answer ppp-209-87-226-0.storm.ca and static-209-87-227-255.storm.ca, with the label first.
• Newer blocks answer 104-192-233-0.ppp.storm.ca and 199-167-118-254.static.storm.ca, with the same label moved into a subdomain.
• Netnames take the form STIN-209-87-224-0, naming the start of the parent allocation rather than the block.
• 199.246.50.0/23 is netname DOCUWEB, registered to a different company.
• The IPv6 list under 2607:f0b0:: runs /45, /45, /44, /43, /42, /41, /40, /39, /38, /37.

Interesting

• The same operator built its reverse zone twice. In the first scheme the access type is a prefix on the hostname; in the second it is a zone of its own. Both are live, and which one an address gets depends on when its block was acquired, so the DNS is a rough timeline of the company's purchases.
• Several non-adjacent prefixes share one netname pointing at a single starting address. The label records where the space came from, not what was announced, which is why it repeats.
• The IPv6 ladder starts with two blocks of the same size before the doubling begins, the signature of a splitter handling a remainder at the start of a range.
