Network type: education

AS11838 announces 4 IPv4 prefixes covering 2,048 addresses and 0 IPv6 prefixes.

About this network

HGTC-ASN belongs to Horry-Georgetown Technical College, a public two-year technical college in South Carolina's coastal Horry and Georgetown counties, with campuses around Conway, Myrtle Beach and Georgetown.

What it's used for

• Campus networking for a community-college system: classroom, lab, library, administrative and student-facing services across its sites.
• RIS observes four IPv4 prefixes carrying about 2,048 addresses, no IPv6, and a single observed neighbour. One upstream and four /23s is exactly what a small institution that wants its own AS number looks like. There is no peering fan-out and no sign of transit or hosting activity.

Notable

• Every announced block registers to the college itself: three 165.166.x /23s and 199.5.206.0/23 under the older NETBLK-SC-HORTECH handle. First-party registrations across the whole inventory, one RIR, no third-party names anywhere. Nothing broker-shaped and nothing leased.
• The three 165.166.x blocks sit inside a /16 that ARIN shows allocated to Spirit Communications in Columbia, South Carolina, back in 1993. The college's own reassignments inside a state carrier's legacy /16 is ordinary provider SWIP history, and the college is still the registered holder of each /23.

Interesting

• A college this size usually holds an AS number for redundancy or as a legacy multihoming arrangement rather than for scale. With 2,048 addresses and one upstream, this one is doing very little routing work today.
• No PTRs came back on the addresses sampled. That is a fact about the sample, not about the college's DNS, and nothing is inferred from it.
