AS13549 — MERCURY

AS13549 announces 1 IPv4 prefixes covering 8,192 addresses and 1 IPv6 prefixes.

About this network

Five prefixes tiling one range, all under a netname that stamps the protocol version onto space that has an IPv6 sibling.

What it's used for

• A regional network provider. 8,192 addresses across five IPv4 prefixes, the IPv6 block 2604:8fc0::/32, and four observed BGP neighbours.

Notable

• The prefixes are a /20, a /21, a /22 and two /23s, all inside 64.7, laid end to end with no gaps.
• All five carry the same netname, MERCURY-V4-1, registered to the company.
• Seven of fifteen sampled addresses answered, each as the address with hyphens under mercury.net.
• The sampled names end in .254, .126 and .128, addresses that sit at small subnet boundaries.

Interesting

• One registry object split into five announcements that exactly cover it is deaggregation for its own sake, or the residue of a plan to steer pieces separately that was never finished. Four upstreams make the second reading plausible in a way a single-homed network would not.
• Numbering the netname V4-1 while holding a full IPv6 /32 is unusual bookkeeping: most operators who stamp the version onto IPv4 never register the other half, and this one did.
• Answers clustering at .126, .128 and .254 are gateway addresses of subnets carved out of the block for individual customers. The generated names are uniform, but which ones exist is not.
