About this network

Contact handles built as a hierarchy: country, then sector, then federal state.

What it's used for

• The IT service centre of a German city-state government. 65,536 addresses in one IPv4 prefix, one IPv6 prefix, and ten observed BGP neighbours.

Notable

• The single prefix is 141.15.0.0/16, netname BLNADM.
• Its registry contacts are DE-GOV-BE Admin, DE-GOV-BE Tech and DE-GOV-BE Abuse Contact.
• The IPv6 announcement is a /32.
• Three addresses were sampled and none returned a name.

Interesting

• Those contact handles are structured where almost every other record in this range is not: a country code, a sector, a state code, then a role. Read left to right they place the organisation in a national scheme, which means other German public bodies can be found by pattern rather than by name. Nothing in the registry requires or enforces this; someone imposed it.
• BLNADM compresses a city and a function into six characters, the older habit that the structured contacts replaced. Both conventions sit in the same record.
• A whole /16 announced as one prefix through ten neighbours is a public-sector network built as a single addressing plan rather than assembled from whatever was available. Government allocations from this era were generous and are rarely subdivided afterwards.
