Summary
Port of Houston Authority
government legacy
PORTO-18-4891 is the Port of Houston Authority of Harris County, Texas, the public agency that operates the port's terminals and the Houston Ship Channel.
What it's used for
- Connectivity for the Authority's own operations: administrative offices, terminal facilities and port systems along the ship channel.
- A single small block, announced for the Authority's own use rather than resold. This is a government end-user network, not a provider.
Notable
- The Port of Houston Authority is a political subdivision of the State of Texas, so this is public-sector address space even though the port operates commercially.
- The low AS number carries no early-internet pedigree. ARIN registered it to the Authority in 2018, from reclaimed space.
Interesting
- Port authorities increasingly run their own AS because terminal operations, gate systems and security infrastructure need carrier-independent, multihomed connectivity across a physically sprawling site.
