AS29878 — CHMP-ASN

AS29878 announces 2 IPv4 prefixes covering 8,200 addresses and 1 IPv6 prefixes.

About this network

The AS handle CHMP-ASN is held by Community Hospital of the Monterey Peninsula.

What it's used for

• The address space carries internal hospital infrastructure, evidenced by netnames CHOMP and reverse DNS entries like chomp-sw-1.cenic.net and chomp--sol-agg4-10g.cenic.net.
• The AS announces 8200 IPv4 addresses across 5 prefixes and 1 IPv6 prefix, with only 3 observed neighbours, indicating a small, self-contained enterprise network rather than a transit or access provider.

Notable

• Registrants for the four largest prefixes are listed as Community Hospital of the Monterey, while the smallest prefix (137.164.40.64/29) is registered to CENIC with netname CALREN, suggesting a leased or transit segment from the regional network.
• The address inventory is finely subdivided into four contiguous blocks in the 204.179.192.0/20 range plus a small /29, consistent with internal site segmentation for a single corporate entity.
