AS14574 — RTCCOM

AS14574 announces 2 IPv4 prefixes covering 12,288 addresses and 1 IPv6 prefixes.

About this network

One reverse name carries a four-letter code after the address; its neighbour in the sample does not.

What it's used for

• A rural telephone company's internet network. 12,288 addresses across two IPv4 prefixes plus one IPv6 prefix, 2607:a700::/32, with two observed BGP neighbours.

Notable

• 216.176.96.0/19 carries the netname RTCC-NB-1 and 168.75.192.0/20 carries RTCC, both registered to RTC Communications, with an Internet Systems Manager contact on the first.
• Two of six sampled addresses returned a name: 216-176-119-254-WAGF.rtccom.net and 168-75-203-254.rtccom.net.

Interesting

• The four letters appended to one hostname are a site code, and their absence on the other says the two blocks were built at different times under different conventions. Nobody goes back to rename the older zone once the addresses are working.
• Holding two blocks from unrelated ranges, one of them from the low 168 space, points at allocations made years apart. A telephone company that has been selling internet access since dial-up accumulates address space the way it accumulates copper.
• A full /32 of IPv6 alongside 12,288 IPv4 addresses is the standard allocation regardless of size, so a small operator ends up with more IPv6 than it could use in several lifetimes.
• Two neighbours is the minimum that counts as multihomed, and it is the usual answer for a rural carrier: one primary upstream, one that exists so the first one can fail.
