Summary
Grande Communications Networks, LLC
isp legacy
GRANDECOM-AS1 is Grande Communications Networks, the San Marcos, Texas cable and fibre operator that now trades as Astound Broadband powered by Grande. It serves internet, TV and phone across Texas markets including Austin, San Antonio, Dallas and Corpus Christi.
What it's used for
- Residential and small-business broadband. This is the eyeball AS: reverse DNS on its space is dominated by subscriber pools such as
…dyn.grandenetworks.netand…static.grandenetworks.net. - It also carries business-access space inherited through the Astound group, with hostnames still bearing older brands like
megapath.netandglobalcapacity.com.
Notable
- The routed footprint is large for a regional operator: roughly 1,700 prefixes and about 1.2 million IPv4 addresses, almost all of it end-user access rather than servers.
- Grande was folded into the Astound Broadband group (alongside RCN, Wave and enTouch) and rebranded, but the original 1996 ARIN ASN and its
grandenetworks.netnaming survive in the routing table.
Interesting
- Because the AS spans several acquired networks, a single reverse-DNS sweep of AS7459 turns up four different legacy provider domains. The routing table remembers corporate history long after the marketing does.

Classification and threat
Residential Fixed-line consumer ISP. Addresses here are homes.
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: 442 networks and 1,771 prefixes, as published 2026-10-15. 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.
