AS13898 — SMART-MOBILE

AS13898 announces 1 IPv4 prefixes covering 1,024 addresses and 1 IPv6 prefixes.

About this network

One block, one upstream, one IPv6 prefix: about as small as an autonomous system gets.

What it's used for

• A mobile operator's network. 1,024 addresses in a single IPv4 prefix, one IPv6 prefix, and one observed BGP neighbour.

Notable

• The IPv4 block is 104.37.192.0/22, netname SMART-MOBILE-LLC, registered to Smart Mobile LLC.
• The IPv6 prefix is 2602:f97c:1::/48.
• The AS handle, the netname and the registrant all name the same company.
• Three addresses were queried for reverse DNS and none returned a name.

Interesting

• A single upstream means the AS number buys portability rather than resilience. Running your own number and holding your own block lets an operator change carrier without renumbering a single device, which for a network selling connectivity onward is worth more than the second transit link it did not buy.
• Every field of the record agreeing is rarer than it sounds. Most networks this size announce space registered to a carrier, a colocation operator or a former parent, and the disagreement is the usual case rather than the exception.
• A /48 of IPv6 alongside a /22 of IPv4 is the standard pairing for a network of this size, and it gives the operator more IPv6 addresses than it will use against IPv4 space it has to ration.
