AS10916 — FIRSTVOLUNTEER
AS10916 announces 1 IPv4 prefixes covering 256 addresses and 0 IPv6 prefixes.
About this network
FIRSTVOLUNTEER belongs to First Volunteer Bank, a community bank headquartered in Chattanooga, Tennessee, which now trades as Builtwell Bank. This is a corporate enterprise network, not a service provider.
What it's used for
The AS originates exactly one IPv4 prefix — 104.128.164.0/24, 256 addresses — with no IPv6 and only 2 observed neighbours. That is the textbook multihomed-enterprise shape: a single provider-independent /24 announced to a pair of upstreams purely so the bank's public services stay reachable when one circuit fails. The address count is far too small, and the neighbour count far too low, for anything resembling a carrier or a hosting business.
Notable
The two sampled PTRs tell the whole story between them. 104.128.164.133 resolves to ciscoesa.builtwell.bank — a Cisco Email Security Appliance sitting under the bank's own .bank domain, which is exactly the sort of edge box (mail gateway, VPN concentrator, remote-access portal) that justifies an enterprise running BGP at all. It also confirms the rebrand: the legal holder is still registered as First Volunteer, but the live infrastructure answers as Builtwell.
Interesting
The other sample, 104.128.164.5, resolves to host-104-128-164-5.ftb.epbfi.com — the default naming of EPB Fiber Optics, Chattanooga's municipally owned fibre utility. The bank's own address space is wearing its upstream's generic reverse DNS. That is a clean, small-scale demonstration of a rule that trips up a lot of network classification: rDNS shows who carries a block, not who holds it.
