AS12782 — Uppsala Lans Landsting

AS12782 announces 9 IPv4 prefixes covering 11,264 addresses and 1 IPv6 prefixes.

About this network

Nine prefixes of legacy 192. space run by a regional health authority, under two names for itself.

What it's used for

• Networking for a Swedish regional authority. 11,264 addresses across nine IPv4 prefixes, one IPv6 prefix, and two observed BGP neighbours.

Notable

• Seven of the nine blocks sit in 192., including 192.36.32.0/23, 192.36.104.0/24 and 192.121.175.0/24; the largest is 195.252.0.0/19.
• Netnames name the organisation twice over: SE-AS-NEW-LAN and SE-AS-MED-2 are registered to Region Uppsala, while the AS itself is held by Uppsala Lans Landsting.
• 192.36.32.0/23 is registered to Resilans AB, a different company.
• The IPv6 announcement is 2a01:58:20::/47.
• One RDAP lookup, for 192.165.148.0/22, failed.

Interesting

• The holder name and the netnames disagree because the organisation was renamed. Swedish county councils became regions, and the registry shows both eras at once: the AS carries the old name, newer blocks carry the new one. Nobody goes back to rewrite records that still work.
• MED in SE-AS-MED-2 is the clue to what this network actually carries. A regional authority in Sweden runs hospitals, and hospital networks are numbered separately from administrative ones because they answer to different rules about who may reach them.
• Seven separate 192. blocks is the signature of an organisation that has been online since addresses were handed out one /24 at a time. None of them can be aggregated, so this network costs the global routing table nine entries to reach 11,264 addresses.
• A /47 does not fall on a 4-bit boundary, so its reverse zone cannot be delegated in one piece.
