What it's used for

• The address space carries content delivery and web acceleration services, evidenced by netnames like NUCDN-ARIN-1 and NUCDN-ARIN-2, and reverse DNS entries such as lo0-0.bfr1.lhr1.as23393.net and mx2.anti-error.com.
• With 13312 IPv4 addresses announced across 13 prefixes and 15 IPv6 prefixes, the network maintains a moderate footprint. The presence of 13 observed neighbours suggests a role focused on content delivery and peering rather than pure transit or residential access.
