AS10399 AMAP-AUSTIN-TX-WALLER
Unclassified ARIN
Summary
Waller Creek Communications
AMAP-AUSTIN-TX-WALLER is registered to Waller Creek Communications, an Austin, Texas entity whose name comes from the creek that runs through the University of Texas campus and downtown Austin. The routing shows it is not an independent commercial ISP.
What it's used for
RIS observes two IPv4 prefixes carrying 33,024 addresses and one IPv6 /48 (2605:2800:3ff::/48). The two v4 prefixes are 205.165.128.0/17 — a large legacy block — and a single 192.12.22.0/24.
Two things pin the network down. First, the registry: both IPv4 blocks are ARIN-allocated to the University of Texas System, not to Waller Creek Communications itself. Second, the topology: there is exactly one observed BGP neighbour, and it is the Texas Department of Information Resources network (AS6922), the state's shared telecommunications programme that carries university and public-sector traffic.
Notable
The kind is education / public sector. A single upstream, that upstream being the state's own network, and address space held by the UT System together mean this AS exists to originate university-affiliated space rather than to sell service to the public. A commercial provider does not single-home to a state agency and does not announce someone else's registry allocations with the registrant's blessing.
Treat the holder name as a legacy label. The handle predates the current arrangement, and the address registration is the honest evidence about who this space belongs to.

Reputation
Classification and threat
Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.
Spamhaus DROP
Not on ASN-DROP The network as a whole is not listed.
No DROP prefixes None of its announced space is on the DROP prefix list.
Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 443 networks and 1,779 prefixes, as published 2026-10-24. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.
FBI IC3
No IC3 indicators Nothing from the FBI IC3 feed.
IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
