AS11738 BLIP-NETWORKS

BLIP-NETWORKS is BLIP Networks, LLC, a fixed-wireless broadband provider based in Murphysboro, Illinois. It serves rural and small-town southern Illinois with wireless internet, plus VoIP phone service, to homes and businesses.

What it's used for

Subscriber access. RIS sees 9 IPv4 prefixes, 4,608 addresses, 1 IPv6 prefix (2605:a1c0::/32), and 2 observed neighbours. The shape is a textbook small regional ISP: enough addresses to number a few thousand customer endpoints, and almost no peering, because a WISP of this size buys transit from one or two upstreams and does not sell connectivity onward. The neighbour count is the honest role signal here and it rules out any transit reading.

Every announced prefix registers in ARIN to BLIP Networks itself: BLIP-NETWORKS-01, BLIP-NETWORKS-02, and BLIP-CGNT-NET-1 / BLIP-CGNT-NET-2. Registrant equals announcer throughout, so there is no leased or third-party space in the inventory.

Notable

The BLIP-CGNT-* handles cover the 38.21.128.0/21 and 38.129.94.0/23 blocks. Those sit in Cogent's 38/8, and the handle names them accordingly: this is Cogent-assigned space SWIPed to BLIP as a customer, then originated by BLIP's own AS. That is provider-assigned addressing, entirely normal for a small ISP, and it is not a broker tell.

The one sampled PTR, pbx.blipnetworks.net on 66.97.116.5, is a first-party hostname for the VoIP switch behind the phone product the company sells.

Interesting

The IPv6 allocation is a full /32, which is the standard ARIN ISP-sized block and far more address space than the entire IPv4 footprint. A rural WISP holding a /32 confirms the ISP posture on paper as clearly as the routing does in practice.
