AS13652 — HORIZON-BLUE-CROSS-BLUE-SHIELD-OF-NJ

AS13652 announces 7 IPv4 prefixes covering 2,304 addresses and 0 IPv6 prefixes.

About this network

Seven prefixes carry six different netnames, one of which spells the block's own address in hexadecimal.

What it's used for

• A health insurer's network. 2,304 addresses across seven IPv4 prefixes, two observed BGP neighbours, and no IPv6 announced.

Notable

• 108.179.9.0/24 is netname CVNET-6CB30900, which is that block's address written in hexadecimal.
• Three addresses in it answer as 6cb3940.cst.lightpath.net and similar, the same encoding per address, except the third part's leading zero is dropped.
• 67.98.95.0/24 is netname LVLT-HORIZO-44-67-98-95: a provider prefix, the company name cut off mid-word, then the address.
• 12.149.40.0/24 is netname HORIZON334-40, and 12.181.129.0/24 is netname ATT.
• Two blocks share netname HORIZONBLUE, and one registry lookup failed.

Interesting

• The hexadecimal encoding is a cable operator's convention, and it survives here on space a hospital insurer runs, so the address is legible to a machine and opaque to a person.
• The netname keeps the leading zero and the reverse record drops it, which means two systems at the same provider encode the same address to different lengths.
• Six netnames for seven blocks records six separate purchases from four suppliers, with the company's name spelled differently in nearly every one.
