Backlink value

bklinkBV$596per link · level B · strength 85

A followed editorial link from developer.mozilla.org would be worth up to $1,193 under BV 2.5, before relevance: its Site Strength is 85 out of 100. The link it usually gives is level B, worth about $596 — and relevance to the site it points to moves that between $298 and $746.

Server and network

developer.mozilla.org is served through Fastly (CDN), a content delivery network. Its address is shared edge infrastructure used by unrelated sites, so it cannot show who else runs on the same server, and sharing the network is no sign of a connection.

CDNedge address, not a server
68on the same hosting network

Fastly (CDN) fronts millions of unrelated sites, so sharing it says nothing about who runs a site. The count is shown; the sites are not listed.
