AS5058 NRL-EXP

NRL-EXP is a United States Navy autonomous system. ARIN lists the registrant as

the Navy Network Information Center (NNIC) in Virginia Beach, Virginia.

What it's used for

• Navy network infrastructure. The handle points toward the Naval Research Laboratory's experimental networking work, but the registry record itself gives no operational detail beyond the Navy registrant — and handles routinely outlive the arrangement that named them, so this card does not read more into it.

Notable

• The AS carries a full /16 — 65,536 addresses — which is government and military space, not commercial.
• NNIC is the Navy's registry-facing organization; many Navy and wider DoD networks are administered through similar central registrant records rather than by the operating command.

Interesting

• The Naval Research Laboratory is the Navy's corporate research lab and was an active participant in internet protocol research during the era this AS was registered. ARIN registered AS5058 in 1995.
