Summary
LightWave Networks
hosting datacenter business legacy
A Dallas hosting and colocation provider.
What it's used for
- Customer hosting. 1,280 addresses over three prefixes, three IPv6
/48s, and thirteen observed BGP neighbours.
Notable
- Thirteen neighbours against 1,280 addresses is a lot of interconnection for a small footprint, which is what selling colocation in a carrier-dense market looks like.
- The three IPv6
/48s come from two different/32s —2606:b600and2607:6b80— rather than from one allocation. - Reverse DNS uses two different schemes at once. Names in
104.232.32.0/23spell the whole address,host104-232-32-128.lightwavenetworks.com, while names in the107.161blocks use the last octet only,host128.lightwavenetworks.com.
Interesting
- The short scheme cannot survive the network it is in. Last-octet-only names give 256 possibilities across prefixes holding 1,280 addresses, so it runs out four times over. The longer form in the other block is the same idea done after someone noticed.
- Dallas is one of the handful of US cities where a small provider can reach a large number of networks without buying long-haul capacity. The thirteen neighbours are less a property of this company than of the building it is in.

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: 431 networks and 1,768 prefixes, as published 2026-10-12. 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.
