I would not be so sure that LANET-1 ASN has anything to do with LANET-1 
Network or with LANET organization id. When ARIN was setting up names for 
organizations, networks, etc, it was doing it out of first two letters of 
company name, plus net plus a number. This would not be the first time 
that different companies got same name for asn and netblock, nor would 
such be considered an error in their database, though if any of these 
organizations report such to arin and request different network name, 
they will do it to remove the confusion.

A quick check shows that State of Louisiana has a number ip blocks with 
names lanet* and they are all linked to ASN2048:


OrgName:    State of Louisiana
OrgID:      STATEO-4
Address:    Department of Health and Hospitals
Address:    Information Services
Address:    PO Box 3013
City:       Baton Rouge
StateProv:  LA
PostalCode: 70821
Country:    US
RegDate:    1992-08-24
Updated:    1994-04-25

Resources Used By Organization:
State of Louisiana (AS2048) LANET-1 2048
State of Louisiana LADOA (NET-192-206-109-0-1) -
State of Louisiana LANET8 (NET-192-239-252-0-1) -
State of Louisiana LANET9 (NET-192-239-253-0-1) -
State of Louisiana LANET10 (NET-192-239-254-0-1) -
State of Louisiana LANET3 (NET-198-51-207-0-1) -
State of Louisiana DHHLA (NET-198-203-166-0-1) -

Given the above I would suspect that if state of louisiana indeed had, it would be linked to their main organization id (given that 
all blocks that were obtained earlier were) and it is not.  This does not 
necessarily means this was not their block, it just the same that we do 
not know it for certain and have no good evidence either way.

"LA" is also often used to represent names for organizations with names 
beginning with "Los Angeles" (and organization "Los Angeles Network ..." 
would get first priority on LANET name). In particular here is what I find 
in ARIN database as well:


OrgName:    County of Los Angeles
OrgID:      CLA-6
Address:    Internal Services Department
Address:    9150 E. Imperial Hwy
City: A     Downey
StateProv:  CA
PostalCode: 90242
Country:    US

NetRange: -
NetName:    LANET
NetHandle:  NET-159-83-0-0-1
Parent:     NET-159-0-0-0-0
NetType:    Direct Assignment
NameServer: DNS1.CO.LA.CA.US
RegDate:    1992-03-20
Updated:    1998-02-18

Now the block in question ( is listed for "ISD", unfortunetly 
ARIN creates names the first letters of first 3 words in organization names
are used for acronym, so there are lots of names beginning with ISD in their
database (like "Intelligent Systems Designs", "Interlake School Division", 
"Information Services Department", etc). Its more interesting to look at 
networks that are assigned to organizations that have name "ISD":


Innovative Systems Design ISD (NET-204-107-85-0-1) -
ISD LANET-1 (NET-170-208-0-0-1) -
isd UU-65-212-131-192-D3 (NET-65-212-131-192-1) -
ISD 625 - ST PAUL PUBLIC SCHOOL Q0904-205-215-222-0 (NET-205-215-222-0-1) -
ISD Corporation PBI-CUSTNET-3996 (NET-216-100-252-0-1) -
ISD CORPORATION QWEST-65-115-100-0 (NET-65-115-100-0-1) -
ISD CORPORATION Q1209-63-149-253-0 (NET-63-149-253-0-1) - 63.149.25R.127
ISD NORTH DAKOTA FON-106830092861637 (NET-63-172-250-128-1) -
ISD DSLNET-20001206-00128 (NET-64-205-53-128-1) -
ISD 709 CPINTERNET-21 (NET-209-240-238-16-1) -
ISD Inc SBCIS-101912-131748 (NET-66-73-231-96-1) -
ISD Inc SBC068078085176030328 (NET-68-78-85-176-1) -
ISD Infotech pvt Ltd. STPH16 (NET-196-12-47-0-1) -

Looking into various addresses I find that "ISD Corporation" has locations 
in Riverside (CA), Corona (CA) and San Jose (CA). Two of these addresses 
are in LA area, so they would be my first choice what ISD stands for for 
that block, but it does look like ISD Corporation has not been in involved 
in internet until recently, but maybe there was some very old history 
there now forgotten. In any case I would more likely suspect that LA in 
that block stands for Los Angeles then for Louisiana. But overall in ARIN 
records I can not find any conclusive answer what company this block was 
originally used at.
